Question

A charge of `9 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `27 J` to `3 J`, what is the voltage between points A and B?

Answer 1

`2.67V`

Explanation:

Form definition, the voltage or potential difference between any 2 points in an electric field or electric circuit is the work done per unit charge to move a charge between the 2 points.

`therefore V=W/Q`

`=(27-3)/9`

`=2.67V`
