electromotive force

1. The force that makes electrons move to produce an electric current. Electromotive force is supplied by a power source, such as a battery or dynamo. It is measured in volts.
2. The difference in the potential energies of a cathode and anode immersed in the same solution of electrolytes or connected in another manner.
