Question

A charge of `8 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `28 J` to `15 J`, what is the voltage between points A and B?

Answer 1

`13/8 V`

Explanation:

By definition, voltage is the electric potential difference per unit charge. We can say, `DeltaV = (DeltaE)/C`

Hence, `"the voltage" = ((28-15)J)/(8C)=13/8 V`
