The electric potential produced by an electrochemical cell or by changing the magnetic field is referred to as electromotive force.
EMF is an abbreviation for electromotive force.
Energy is converted from one form to another using a generator or a battery.
When no current flows, the electromotive force (EMF) equals the terminal potential difference. Although both EMF and terminal potential difference (V) are measured in volts, they are not the same thing. Emf is not affected by the internal resistance of the circuit.
The amount of energy (E) provided by the battery to each coulomb of charge (Q) passing through is referred to as the EMF.
