WebAug 31, 2024 · What is emf of a cell in chemistry? Electromotive Force (EMF) The electromotive force (EMF) is the maximum potential difference between two electrodes of a galvanic or voltaic cell. This quantity is related to the tendency for an element, a compound or an ion to acquire (i.e. gain) or release (lose) electrons. WebFeb 28, 2024 · Electromotive force is the characteristic of any energy source capable of driving electric charge around a circuit. It is abbreviated E in the international metric system but also, popularly, as emf. Despite its name, electromotive force is not actually a force.
