Question

Define emf of cell??????????????

Answer 1

Explanation:

The voltage or electric potential difference across the terminals of a cell when no current is drawn from it. The electromotive force (emf) is the sum of the electric potential differences produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell.

Answer 2

Electromotive force of a cell ( E.M.F ) :- It is the maximum potential difference between the two electrods of the cell when no current is drawn from the cell or cell is in the open circuit.
