Electromotive force or E.M.F. is the maximum voltage that can be attained by a specific circuit. EMF is the maximum voltage that can be attained by a specific circuit.
Potential difference is the work done per unit charge to move a charge between the negative and the positive terminal of the battery. When the battery is in use, or the circuit is closed, a small portion of the emf is spent in overcoming the internal resistance of the battery. This energy per unit charge is called potential difference.
Hence, EMF is most closely related to the potential difference.
