Text Solution

Verified by Experts

The correct Answer is:
D
The electrical force of a cell of bettery called electromotive force (emf).This force,which makes electrons flow around a circuit.Each kind of cell has a particular emf.The size of a cell has no effect on its emf.The chemicals in the cell determines its emf,but large cells last longer than samll cells of same basic type.This means that from a large cell,we a particular emf for more time as compared to small cell.
