Question

A charge of `16 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `54 J` to `12 J`, what is the voltage between points A and B?

Answer 1

The voltage is `=2.625V`

Explanation:

The charge is `Q=16C`

The variation in the charge electric potential is

`DeltaW=54-12=42J`

The voltage is `DeltaV=(DeltaW)/Q=42/16=2.625V`
