Answer 1

Electromotive Force Definition: Electromotive force is the electric potential generated by either a electrochemical cell or a changing magnetic field. ... The SI unit for electromotive force is the volt. Also Known As: voltage, emf. Helmenstine, Anne Marie, Ph.D. "Electromotive Force.

Answer 2

The electromotive force or e.m.f. is the energy provided by a cell or battery per coulomb of charge passing through it, it is measured in volts (V). It is equal to the potential difference across the terminals of the cell when no current is flowing.
