Introduction to Electromotive Force. Voltage has many sources, a few of which are shown in Figure (PageIndex{2}). All such devices create a potential difference and can supply current if connected to a circuit. A special type of potential difference is known as electromotive force (emf).The emf is not a force at all, but the term ''electromotive force'' is used for historical reasons.
