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.

If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current - a flow of charge. Using the word current in this context is to simply use it to say that something is happening in the wires - charge is moving. Yet current is a physical quantity that can be measured and expressed numerically.
