# Sample Physics Essays On Electric Field And Circuit

### Homework Question on Electric Field And Circuit

• Select a concept or issue that was covered in lecture and formulate a question (see examples at the end of this document).
• This question should be stated explicitly in your assignment, either as the title or in the first paragraph.
• Select the relevant information from class notes and the textbook, and write a 1-2 page essay (double-spaced, Word ONLY [.doc or .docx], no PDFs)
• Write an essay addressing this question and discuss the relevance of the concept or issue to helping a community to which you belong.
• Be sure to include some concrete information that was covered in this unit, explaining why this specific information is relevant to, or useful for, helping your community.

Here are some examples of questions you could address:

1. How can knowledge of momentum be used for a more efficient public transportation system?
2. How can electromagnetic radiation be used for imaging techniques to diagnose disease?

Here is an example of an approach you could take:

If A Student had been learning about momentum in this course, and was writing this essay, they might choose this topic, and then relate it to their community in the following way: “When I learned about momentum in this course, I found out that momentum can be transferred or conserved during motion. I also now know that changes in momentum usually signals a change in velocity. By better understanding how to keep trains at a certain velocity, we can learn how to build more energy efficient trains. More energy efficient public transportation systems, like trains, could lower the cost of transportation. Now that I have learned more about momentum, I think that this information could be used to help people from my own community to have more affordable public transportation.

How useful is electric field and circuits to my community?

### Homework Answer on Electric Field And Circuit

I learned the concept of electric field explaining that a charged body would always have effects on the region that surrounds it. In case another object enters this area, then it will be affected depending on whether it is charged or neutral and the type of charge it is. It should be noted that a charge interacts with an electric field rather than just another charged body. The field is represented by patterns of lines as was discovered by Michael Faraday.

The electric field in relation to a charge interacting with a charge would lead to the formulation of voltage and potential difference. A potential difference would result in the flow of current through a circuit.On the other hand, a circuit is the path through which current flows. Usually, a circuit has various components without which it becomes useless. Electricity will flow in the presence of the source of a voltage called a battery, which can be active or passive components.

Conductors are used for wiring to allow conduction of charge along the circuit. The knowledge of electric field is very important in the society because, people would learn that charged materials are not supposed to be exposed in an electric field because they would interfere with the source of field negatively in most cases. For example, lighting discharges and can kill anytime if the charges run through human body.
