Question

Go to http://wps.aw.com/aw_knight_physics_1. Use the pull-down menu in the top left corner of the screen to go to Part VI. Electricity and magnetism, and then find lesson 11.11: Electric potential- Qualitative introduction. Open the lesson and start working on Questions 1-5. After you are done, answer the following questions.

1. What will happen to negatively charged particle placed between points that have electric potentials 0V and 9 V? Explain.

2. Discuss the meanings of the words " potential," " potential difference", and "voltage". Give examples to help illustrate. What you're talking about.

3. How can the knowledge of electric potential help us understand the motion of electrically charged particles in electric circuits?

4.

Explanation / Answer

1. Electric potential is the amount of potential energy per unitcharge that a test charge would feel at a given location. Voltage is the difference in electric potential.
