Scientific definitions for circuit

circuit

[ sûr′kĭt ]

A closed path through which an electric current flows or may flow.♦ 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.

A system of electrically connected parts or devices.
