For other uses, see EMF (disambiguation). Electromotive force, also called emf (denoted E {\displaystyle {\mathcal {E}}} and measured in volts), is the voltage developed by any source of electrical energy such as a battery or dynamo. It is generally defined as the electrical potential for a source in a circuit.
John, let's sort out electrical units for you, The unit of EMF or PD is the Volt after an Italian who 'invented' the first battery The unit of current is the Ampere after a Frenchy who was first to measure current flow The unit of resistance is the Ohm, after an Austrian G.S. Ohm who first recognised this property in a conductor.
