Question

A charge of `25 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `32 J` to `25 J`, what is the voltage between points A and B?

Answer 1

The voltage is `=0.28V`

Explanation:

The potential difference between the points `A` and `B` is `=U`

Voltage =Energy/Charge

`U=(DeltaE)/Q`

`DeltaE=32-25=7J`

The charge is `Q=25C`

`1 V=(1J)/C`

`U=7/25=0.28V`
