Question

The potential energy of a +5.00 10-6 C charge decreases from 0.06 J to 0.02 J when it is moved from point A to point B. What is the change in electric potential between these two points?

Answer 1

the 0.06 J to 0.02 J potential energy drops refers specifically to the charge in question. but you can calculate the change in electric potential energy that **a charge if 1C** would have undergone in the same circumstances.

that is what is meant by the change in electric potential between these two points. it is measured in volts.

Answer 2

So what kind of formula would I use for this?

Answer 3

V = PE / q
V = potential (volts)
PE = electrical potential energy (joules)
