Question

define emf of a cell. mention two difference between emf and terminal difference

Answer 1

Emf is not a physical force. ... In simple words, it may be stated as electromotive force is the maximum voltage that can be attained by a specific circuit. Potential Difference. Potential difference is the work done per unit charge to move a charge between the negative and the positive terminal of the battery.

Answer 2

Answer:

$\huge\mathfrak\pink{Answer}$

The emf (electromotive force) is the potential difference between the terminals of a battery when no current is flowing through an external circuit when the circuit is open. Potential difference is the voltage across the terminals of the battery when the current is being drawn from it to an external.
