Question

The unit _____ is used to measure electric potential energy; whereas the unit _____ is used to measure electric potential difference.joule, voltvolt, joulenewton, voltnewton, joule

Answer 1

The unit joule is used to measure the electric potential energy; whereas the unit volt is used to measure the electric potential difference. Therefore, first option is correct.

The difference in potentials of two points is known as electric potential difference and the energy which is required by a charge to move from one point to another is electric potential energy.
