Electric circuit Essay Example for Free

Electric circuit Essay Every time a charged atom hits the net it loses some of its charge, therefore the longer the wire the larger the chance of the charged electrons colliding with the net and losing some of their charge therefore increasing the resistance. Width of wire: The width of a wire will affect the resistance because the wider a wire the more space in the net for the charged electrons to get through without colliding with the net and therefore decreasing the resistance. It is like letting a lot of water out of a small hole; it would go slowly, whereas with a bigger hole it flows out faster. Temperature of wire: The temperature of the wire would affect the resistance because as the wire gets hotter the net begins to vibrate because they are given more energy; this therefore makes it harder for the charged electrons to get through the net without colliding with it and causing resistance. Therefore the higher the temperature the higher the resistance. Material of wire: The material of a wire would affect it resistance because different materials have different resistivity because the have different nets. Some of the nets may have smaller holes that others and this would increase the resistance because there would be a larger chance of the atoms colliding. Similarly some materials may have larger nets, which would mean that there would be a lesser chance of the atoms colliding. The variable that I am going to change is going to be the resistance because I think it will be the easiest to change with the apparatus I have available to me and I think it will give fair results. Research So far I have taken a lot of information from my G. C. S. E.textbook but some of my work has come from the Internet. I used many different search engines but the two main engines, which I used, were www. ask. com and www. google. com and here is some of the information, which I got by using these engines: Resistance alloy data Material Nominal Resistivity Microhm. cm Maximum Operating Temp i C Density g/cm3 Nominal Temp Coeffic. of Resistance. This information was very useful because the type of wire I am going to use is Nickel Chrome and it has a lot of information on it and it tells me its resistivity. Prediction I predict that as the length increases the resistance will also increase in proportion to it. I think this because the longer the wire the longer the net of atoms and therefore the larger the chance of the electrons colliding with the net and losing some of their charge. Therefore if the length is doubled the resistance should also double, because the length of the wire has doubled therefore the amount of atoms will have doubled so the amount of collisions should double. When I draw a graph it should hopefully show that the length is directly proportional to the resistance. The diagram below should show this more clearly: Apparatus Meter rule to measure out the length of the wire. 1-meter length of nickel chrome wire to test its resistivity. Ohmmeter to measure the resistance of the wire. Crocodile clips to connect the ohmmeter to the wire. Wires to connect the ohmmeter to the crocodile clips. Masking tape to stick the wire to the ruler. Preliminary Work I did some tests to see what distance I needed to space my readings at and this is what I got: Length (mm) Resistance (ohms) My preliminary results have shown that altering the length by 10mm is too little because the resistance gain is too uneven, but if I change the length by too much i. e. 500mm the gap is too large. Therefore I am going to take my results every 50mm. I also found that the wires connecting the ohmmeter to the wire had a resistance of 0. 3mm so I will have to To make it a fair test I need to make sure that I keep all of the other variables the same. I will use the same wire every time and in I will use it again in my repeat experiment, so that the width and material of the wire will remain the same. The temperature of the wire will be very hard to keep constant because each time an electron collides with the net its energy change from electrical to heat therefore every time the atoms collide with the electrons the wire will heat up. Hopefully this will not affect my experiment too much because I am only going up to a meter in length therefore it should not heat up too much. Diagram My apparatus will be set up like so: Method 1. First I will gather up all the needed apparatus and set it up as above. 2. Then making sure that one of the crocodile clips is on exactly 0mm and that the other is on exactly 100mm I would take a reading. 3. Before I record the reading I would make sure that the ohmmeter had come to a complete stop and was not flashing. 4. I would the repeat this every 50mm until my I got to 1000mm making sure that the first crocodile clip was always on 0mm. 5. Then I would repeat the whole experiment making sure that I used the same wires so that the width and material of the wire were kept constant. 6. Whilst repeating the experiment I would make sure that I did it in the same place as before because if I repeated it next to a radiator the resistance would go up. Results Length Of Wire (mm) Results 1 (Ohms) Results 2 (Ohms) Average (1dp) (Ohms). Explanation Of Results My first set of results has an anomalous result, which is circled on the first graph. This could be because I did not wait for the ohmmeter to settle and I took the reading too quickly. My second and average set of results are good with no anomalous results and they show a definite relation between the resistance and the length of the wir they show that as the length goes up so does the resistance. In my prediction said that if the length doubles so should the resistance and my first set of results show that at a length of 250mm the resistance was 5. 2W and at a length of 500mm the resistance was 10. 1W which is very close to my predicted answer. Conclusion I think that my experiment went quite well because all my graphs had straight lines showing a strong relationship between the length and the resistance. But I could have improved this method in a couple of ways. For example I should have used pointers instead of crocodile clips because they are far more accurate, this is because they have a far smaller tip than crocodile clips and they would give a more accurate measurement of the wire. Also pointers would not have compressed the wire like crocodile clips. Crocodile clips have a spring in the to keep them shut and this could have compressed the wire therefore increasing the resistance. I also should have been more careful about making sure the wire was taught when I took the readings because if it was loose it would have been a longer length that the one I thought I was reading.

Reflection Essay :: Reflection Essay

REFLECTION PAPER Chapter 10 is entitled Conflict Management in Groups. This is a very essential chapter for all members of a group to read and understand. Fortunately, my group members and I have not had a problem with getting along. It just so happened that four members of my group already know each other from another class they are in together. So, they already got along and had some connection with one another. I think we all have good personalities and we enjoy working with each other. The characteristics of our group allow us to be a successful group. The semester is coming to an end, and we have worked hard together to perform all tasks and accomplish all our goals. Getting to the stage where we are now involved a lot of comprimising and negotiating. So, the two terms I would like to concentrate on from Chapter 10 is comprimise and negotiation. To me, comprimise is meeting someone half way. You may have to adjust some of your beliefs or ideas to fit the beliefs or ideas of another group me mber. the book defines comprimise as a middle ground. You show a moderate concern for both task and social relationships in groups. The next term I would like to look at is negotiation. I would define negotiation as giving and taking to reach a common goal. The book’s definition of negotiation is a process by which a joint decision is made by two or more parties. After researching information for my group project and listening to another group’s presentation, it is evident that everyone thinks comprimise and negotiation are very important. There was a strong emphasis on avoiding conflict in the group

Children’s Functional Health Pattern Assessment Essay

Short Answer Questions Address the following based on the above assessment findings. Expected answers will be 1-2 paragraphs in length. Cite and reference outside sources used. 1) Compare and contrast identified similarities as well as differences in expected assessment across the childhood age groups. There are so many differences from the toddler stage to school age. The body and mind go through so many changes. Children are learning so much from being able to drink from a cup, control their bladder and bowels, brushing their teeth, learn values and beliefs, discover independence. There are so many challenges that they may face as they discover the environment around them. The people that they will meet on the playground, in the library, the store and at school, will help shape their lives. As you have seen that the toddler age child needs structure and guidance while they learn how to do everyday tasks on their own. The preschool child still needs structure and guidance but may start to do things on their own like pour their own milk to dressing themselves. The school age child is learning independence, learning how to be independent, seeking there self-concept and sense of identity. 2) Summarize how a nurse would handle physical assessments, examinations, education, and communication differently with children versus adults. Consider spirituality and cultural differences in your answer. A nurse should always introduce themselves first then they need to be calm, speak softly and earn the child’s trust. Children need to know the step by step process of what will happen, they are usually scared and need reassurance. Get to know what they like, if a child brings in a stuff animal, ask the child what the name is. Let them know you care about them, and what they care about. They need to be involved as much as they can in their care. Their parents also need to be involved with whatever is going on with their child. Consider the families cultural differences and spirituality regarding treatment, examinations, assessments, communication. When assessing an  adult you should introduce yourself first, answer any questions they may have regarding their assessment, treatment and any education that may be given. Ask if they want anyone else involved with their treatment. Make sure all their questions are answered. References How a child develops. (2011, January 1).

Health Beliefs in the Latino Culture Essay

Vomiting, fever, crying, restlessness (Evil eyeness), brought on by an admiring or covetous look from a person with an evil eye. All children are susceptible. Prevented if the person with the strong eye touches the child when admiring her/him; also by wearing particular earrings, necklaces, or other jewelry. Treated with a barrida (Puerto Rican) or limpia (Mexican) which is a spiritualistic sweeping of the body with eggs, lemons, and bay leaves, accompanied by prayer. Barrida/limpia are believed to have treatment value. Susto Anorexia, insomnia, weakness, fright disease hallucinations, and various painful sensations, brought on by traumatic situations such as witnessing a death. Treatment may include a barrida (see mal de ojo), herb tea and prayer. Caide de mollera A condition thought to cause fallen, sunken anterior fontanella, crying, failure to suckle, sunken eyes, vomiting. Popular home remedies include holding the child upside down over a pan of water, applying a poultice to the depressed area of the head, and/or inserting a finger in the child’s mouth and pushing up on the palate. Empacho Lack of appetite, stomach ache, diarrhea, and vomiting caused by poorly digested food, or uncooked food sticking to the walls of the stomach and/or digestive tract. Treated by massaging the stomach; drinking a purgative tea (estafiate); or by azarcon or greta,   medicine that has been implicated in some cases of lead poisoning. Ataque Severe expression of shock, anxiety or sadness, characterized by mutism, hyperventilation, bizarre behavior, hyperkinesis, violence, and uncommunicative behavior. A culturally appropriate and sometimes expected emotional response to shocking or unexpected news. Bilis Vomiting, diarrhea, headaches, dizziness, migraine headaches, nightmares, loss of appetite, and the inability to urinate brought on by livid rage and revenge fantasies. Believed to stem from bile pouring into the bloodstream in response to strong emotion, resulting in an imbalance of â€Å"yellow bile† and the person â€Å"boiling over.† Bilongo (hex) Any illness may be caused by a bilongo or hex; proper diagnosis and treatment requires   consulting a Santero/Santera (priest or priestess). Hot and cold theory Health is the product of balance of the four body humors–blood and yellow bile being â€Å"hot† and phlegm and black bile being â€Å"cold.† Diseases are caused by humoral imbalance. Foods and medications will cure disease by restoring the balance. Thus a â€Å"hot† illness is cured with â€Å"cold† medication and food; â€Å"cold† illnesses are treated with â€Å"hot.† Those that believe the common cold is caused by a cold draft entering the body will not drink cold fruit juices because it will add more â€Å"coldness† to the body. However, the provider can recommend more hot teas, broths, and soups for liquids. The family would accept this. Note.

Comparing and Contrasting the Two Major American Political Parties Essays

Comparing and Contrasting the Two Major American Political Parties Essays Comparing and Contrasting the Two Major American Political Parties Essay Comparing and Contrasting the Two Major American Political Parties Essay In the United States there exists largely a dichotomy with respect to parties of political affiliation, and while other parties can and do exist, most people refer to the US as it is now as a â€Å"two-party state. † The two parties, the Democratic Party and the Republican Party, have existed in our country for over one hundred fifty-three years each, and the struggle for power in which they both partake has been no small matter, becoming more and more hotly contested as time goes on. While both the Democratic Party and the Republican Party (GOP herein) seem starkly opposite at surface level, the two often have similar goals, aspirations and plans for our country, with the main point of contention being the methods by which such things are brought about. Fiscally, the Democrats and GOP both want a free economy with as little national debt as sustainably possible, but, for the most part, the Democrats favor government action, and the GOP favors private action. With respect to social policy, the Democrats favor more progressive legislation, and the GOP favors more traditional legislation. As the US stands currently, in a recession, no American could disagree that everyone’s goal for the economy is to get out of the recession. The real question is â€Å"How do we do it? † Republicans say that we should cut spending, cut taxes and allow those cuts in taxes to promote job creation in the private sector: jobs come from businesses, and when the people who own the businesses have more money, they can hire more people to do more work, which would raise GDP and reduce the national debt. Democrats say that we should raise taxes to increase revenue, and use the increased revenue to sponsor various economic stimuli to promote greater productivity and job creation. This sort of top-down/bottom-up perspective has led many Americans to believe the motivations of the two parties to be a conflict of social classes, with Republicans representing largely the rich, and Democrats representing largely the poor. Undoubtedly, the largest differences between the two major parties exist in the social platforms of each. The GOP is composed mostly of those who are socially conservative, the Democratic Party, of those who are socially liberal, but there are certainly those within each party whose beliefs vary. The Democratic Party generally supports legislation promoting social tolerance, i. e. policies which limit the government’s ability to tell any person what to do, provided that they not infringe upon the rights of others. This amounts to policies in favor of things gay marriage and marijuana legalization and policies opposed to abortion restrictions, welfare drugs tests and public funding of religious institutions and schools. The GOP generally supports social legislation which maintains the status quo, protecting the foundation of America which those before us have provided. In this manner, the GOP usually favors legislation that protects the sanctity of marriage (i. e. ne man, one woman), prevents drug addicts from receiving welfare and prevents people from harming themselves with drug use, and the GOP generally opposes legislation that would allow any of the previous things to occur. Interestingly, however, the GOP strongly supports the exercise of the Second Amendment to its fullest capacity, opposing almost any gun control law, while the Democrats generally favor gun control with respect to some of the more dangerously liable guns such as assault rifles or even some semi-automatic rifles. In terms of demographics and geography, the Democrats and Republicans are quite contrasting. By and large, the Republican Party is most powerful in the South and Midwest, while the Democratic Party gains its power mostly from the North and the West coast. Republicans are more likely to be older, more wealthy, more religious and white (though this obviously does not mean all Republicans are white). Democrats are more likely to be younger, more educated and more ethnically varied than the Republican Party. These snapshots into the average Democrat or the average Republican must be taken with a grain of salt, however, as demographics and geographic are not causes of the party composition, but merely correlations which have been concluded. While the Democrats and Republicans have long been considered bitter rivals, and for the most part it is true, the two major parties in America are not quite as disparate and incongruous as many would think. They both have the same major goals for the economy, but only the methodology differs. They have different ideas for social policy, stemming from the more religious and more secular worldviews which most Republicans and most Democrats respectively hold. With the differences aside from both, the Democrats and Republicans in political offices do come together to prevent the one which they fear most: the success of any third party. Both parties will stop at nothing to maintain whatever power they each have.

The Real Chocolate company Assignment Example | Topics and Well Written Essays - 3000 words

The Real Chocolate company - Assignment Example The company strategically positions its retail stores in tourist environments, regional malls, airports and entertainment oriented sites where it mainly targets outgoing people. Apart from a choice of about 300 chocolates, the company also offers an assortment of other confectionary products. However, its major challenge it is facing is the growing competition from other chocolatiers in the industry. Usually, unfavourable elements within a business environment often threaten its viability and can lead to failure in some cases hence require concerted efforts to counter them. In this particular case, competition from other rival competitors is the major threat to the Real Chocolate Company. According to statistics by the National Chocolate Association, gourmet chocolates in particular account for about 10% of the chocolate industry and there are about 15 competitors in the industry. The major competitors of Real Chocolate Company are Godiva chocolatier with annual sales of five million, Russell Stover as well as See's Candies with an annual sales of five million. Stiff competition can often lead to saturation of markets which would also negatively affect the sales as a result of monotony likely to be created as a result of lack of choice emanating from flooding of the markets. Only very innovative companies stand better chances of winning the hearts of their trusted customers in s uch a scenario which is regarded as a major threat to the operations of a company's business. If the situation is not properly managed, a company can be easily kicked out of business through the loss of customers to competitors. The chocolate and confectionary industry must comply with numerous regulations that cover health, education, sanitary and franchise operations especially with regards to registration and privacy. Things such as labelling must comply with the Nutrition and Labelling Education Act of 1990. Whilst the laws are promulgated to protect the interests of the citizens, in some instances the provisions of some sections of the legislation may be a bit heavy especially on Small Scale Enterprises (SMEs) whose budgets may prohibit full compliance with some of the regulations. Such pieces of legislation often threaten the viability of small scale companies that are still trying to establish themselves in the market. For instance, the prescribed packaging for chocolates can be costly to companies still in their infancy hence it's a threat that needs to be given due consideration. Unfavourable climatic conditions can also negatively affect the chocolate industry in many ways. For example, adverse climatic conditions in areas where the crop which provides the basic ingredient in chocolate production is grown, can lead to negative growth in the chocolate industry. The cocoa bean is the main fruit used hence an outbreak of a disease in the areas where it is produced would mean a slump in production of chocolate. The world is also face with unprecedented climatic changes brought about by global warming. In the event that extreme weather conditions occur, production of cocoa is also likely to be negatively affected which translate into a decline in chocolate production. Natural environmental conditions are uncontrollable in most cases and their effects should not be undermined. Opportunities The Real Chocolate Company is also exposed to certain opportunities which can lead to growth of business. In this case, these include the use of franchise

Discuss the way in which, Montesquieu encourages his readers to Essay

Discuss the way in which, Montesquieu encourages his readers to identify with or distance themselves from the characters in the - Essay Example This literary style and the socio-political content of the novel as told by two foreign figures enabled its readers to identify with the characters at the same time feel separated from their stories and experiences. It also allowed Montesquieu to achieve his objective in writing the novel. Detachment The first prominent variable that affects the way readers perceive and interpret The Persian Letters is its form. As a collection of letters, which contain discourses and essays on diverse issues, it made the novel disconnected to the readers because the emotional involvement is stunted by the interrupted presentation. This is best explained by Theodore Braun who commented that the novel "moves along in an apparently unpredictable manner from letter to letter, from theme to theme, from interior plot to the exterior plot" making the readers fumble particularly in making sense or identifying the coherence of all the parts provided (Runyon 2005, 13). Readers can also feel the detachment whe n Montesquieu used Persian characters in his narrative. Their characterizations were depicted as alien for the original intended reading public. They are Persians and that their way of life and their perspectives on the French lifestyle represent a glaring difference that is easily identified and sympathized with by the readers. Montesquieu, wrote Hulliung (1976), substituted Persian travelers with psyches that are long written full by Eastern culture and that the interaction between the East and the West could lead to the threat on the Eastern language of despotism (117). By transplanting the two Oriental characters in Paris, there was a depiction of a striking polarity in culture and ideas. Say, when Montesquieu portrayed the Persians as exotic, with sufficient allusions to their cultural norms and their harem and so forth, the reader naturally sided with the West and/or the French society and that the two protagonists - including all that they stood for - came to constitute other ness, the unknown and the unidentifiable. There was an imposed detachment that came with the double plot of the novel. At one point, there was the criticism of the Parisian way of life. On the other hand, there was the Oriental storyline (e.g. the disorder in the protagonist's seraglio back home). This approach enabled Montesquieu to highlight his themes more effectively, more specifically the kind of skepticism and relativism that he obviously wanted to express about the important questions that characterized his time. Furthermore, the differences and the detachment that the author encouraged were necessary in order to explain his ideal social theory. This is when Montesquieu was able to successfully reject the European social theory and advocate the actual expression of human nature as the ultimate solution to the issues and problems that confronted his day (Rossides 1998, 72). Connection It is, however, important to underscore that even though The Persian Letters assumed a degree of disconnect from its readers, there are times when its characters - or the themes and issues they discussed and were involved in - came close to the readers’ hearts and own concerns. As a political allegory, the novel explored, examined and commented on themes and issues that are relevant to the times. For example, there is the issue about love, social institutions, gender equality, religion,
