Read the web page: The Electric Potential. To give you some practice on working with electric potential, go to the PhET simulation Charges and Fields to perform a few tasks.

1. Add a positive and negative charge with about 5 cm of space between them. Describe what the electric field looks like.

2. Use the device to plot equipotential lines (locations where the electric potential is the same). Describe what the equipotentials look like.

3. Is there a relationship between the electric field and the equipotentials?

4. What happens if you add more charges?
