Question

A charge of `25 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `25 J` to `21 J`, what is the voltage between points A and B?

Answer 1

`-4/25 V`

Explanation:

Potential Energy `U` and potential or voltage `V` are related as follows

`U = q V`

Thus, here, `Delta V_(AB) = (Delta U_(AB))/q = -4/25 V`
