The simulation below shows how the free electrons are spread out on a conductor when charged. When a conductor is charged - where do charges tend to "crowd"?

What happens to the electric field and the electric field lines when you decrease the voltage? 

What happens to the electric field and the electric field lines when you decrease the distance between the plates (plate separation)?

Task 1: Select "Diple" from premade configurations

1. Select equipotential lines.
2. Click around the charges a few times to generate equipotential lines

Where are the equipotential lines closest together? What does this mean for the electric field strength at that point?

Task 2: Select "Random" from premade configurations

1. Select equipotential lines
2. Click around the charges a few times to generate equipotential lines.

What is the relationship between the field lines and the equipotential lines (what's the angle between them)? Would you be able to construct the electric field lines if you were given the equipotential lines or vice versa?
