Question

A charge of `6 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `24 J` to `9 J`, what is the voltage between points A and B?

Answer 1

`2,5V`

Explanation:

By definition, the voltage (or electric potential difference) between any 2 points in an electric circuit is the work done per unit charge in order to move the charge between the 2 points.

`therefore V=W/Q`

`=(24-9)/6`

`=2,5V`
