[1350–1400; Middle English < Latin circuitus, variant of circumitus circular motion, cycle <circu(m)i-, variant s. of circu(m)īre to go round, circle (circum- circum- + īre to go); compare ambit, exit1]
Bulbs in a series circuit (left) give off dim light since they each consume a portion of the power coming through a single circuit connected to the battery. In a parallel circuit (right) bulbs shine brightly since each is directly connected in its own circuit to the power source.
1. 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), 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.
2. A system of electrically connected parts or devices: a microchip containing all the circuits of a computer.
Circuitthe action of moving round about; those persons making a circuit; used figuratively.
Examples: circuit of judges and barristers, 1494; of deductions, 1594; of reasoning, 1836; of speech, 1605; of words, 1672.
