A closed path through which an electric current flows or may flow. &diamf3; Circuits in which a power source is connected to two or more components (such as light bulbs, or logic gates in a computer circuit), one after the other, are called series circuits. If the circuit is broken, none of the components receives a current. Circuits in which a power source is directly connected to two or more components are called parallel circuits. If a break occurs in the circuit, only the component along whose path the break occurs stops receiving a current.
American Heritage Science

An end-to-end communications path between a transmitter and a receiver. Circuit generally implies a logical connection, or session, over a physical medium. Circuit often is used interchangeably with path, link, line, and channel, although the usage can be specific to the underlying technology, the overall context, and other factors. Circuits can be characterized in many ways. For example, a circuit can be either two-wire or fourwire in nature, for either access or transport applications. A circuit can be simplex, half-duplex, or fullduplex in nature. A circuit can be dedicated, switched, or virtual in nature. A circuit sometimes is referred to in the vernacular as a pipe, as in a broadband pipe. See also channel, four-wire circuit, line, link, path, twowire circuit, and virtual circuit.
