Why is terminal voltage of a cell less than its emf ?

Text Solution

Verified by Experts

emf= Terminal voltage +P.D across internal resistance.
`E=V+Ir`
A cell has always same internal resistance a part of the emf is consumed in doing wire against the internal resistance in a closed circuit
So `E gt V (or) V lt E`
