Question

A charge of `2 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `21 J` to `5 J`, what is the voltage between points A and B?

Answer 1

The voltage is `=8V`

Explanation:

The potential difference =work done/charge

The work done is the electric potential

Work done `=(21-5)J`

Charge `=2C`

Voltage `=(21-5)/2=16/2=8V`
