Question

A charge of `6 C` is passing through points A and B on a circuit. If the charge's electric potential changes from `36 J` to `27 J`, what is the voltage between points A and B?

Answer 1

Voltage is given as the electric potential difference per unit charge.

As: `DeltaV = (DeltaE)/C`

Following this definition, the voltage required is :

`DeltaV = ((36-27)J)/(6C) = 3/2 "Volts"`
