Question

A charge of `9 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `15 J` to `9 J`, what is the voltage between points A and B?

Answer 1

`667mV`

Explanation:

Voltage or potential difference is defined as the work done per unit charge to move charges between the 2 points.

`therefore V=W/Q`

`=(15J-9J)/(9C)`

`=0.667V`#
