Electromotive force is the force, which is able to maintain a constant

A

potentential difference

B

power

C

resistance

D

current

Text Solution

Verified by Experts

The correct Answer is:
A
Emf is not force, it is analouge to potential difference. The energy spent in circulating a unit charge through the circuit is known as electromotive force of the cell. It is expressed as emf in brief.
