Question

A charge of `8 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `32 J` to `4 J`, what is the voltage between points A and B?

Answer 1

The voltage is `=3.5V`

Explanation:

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

Voltage =(Energy)/Charge

`U=(DeltaE)/Q`

`DeltaE=32-4=28J`

The charge is `Q=8C`

`1 V=(1J)/C`

`U=28/8=3.5V`
