EMF of a Cell: The maximum potential difference which is present between two electrodes of a cell is defined as the electromotive force of a cell or EMF of a cell. It’s also known as the net voltage between the half-reactions of oxidation and reduction.
The EMF or electromotive force is the energy supplied by a battery or a cell per coulomb (Q) of charge passing through it. The magnitude of emf is equal to V ( potential difference ) across the cell terminals when there is no current flowing through the circuit.
