Electromotive force is commonly denoted by the acronym emf, EMF or E.
The SI unit for electromotive force is the volt.
Electromotive force in a circuit maintains the potential difference.
Electromotive Force (EMF) makes free electrons to flow in any closed circuit due to difference in electrical pressure or potential. Its unit is Volt.
