A circuit of a place or area is a journey all the way round it. She made a slow circuit of the room. or electric circuit Path that transmits electric current. A circuit includes a battery or a generator that gives energy to the charged particles; devices that use current, such as lamps, motors, or electronic computers; and connecting wires or transmission lines. Circuits can be classified according to the type of current they carry (see alternating current, direct current) or according to whether the current remains whole (series) or divides to flow through several branches simultaneously (parallel). Two basic laws that describe the performance of electric circuits are Ohm's law and Kirchhoff's circuit rules. See also tuned circuit. electric circuit circuit riding integrated circuit Kirchhoff's circuit rules printed circuit tuned circuit
By analogy to the proceeding three, a set of theaters among which the same acts circulate; especially common in the heyday of vaudeville
A full path of electrical current from a voltage source that passes completely from one terminal of the voltage source to another
An electrical connection which, when charged, it magnetizes a piece of metal This circuit is involved in the mechanism which opens the valves to allow pipes to speak in an electric action instrument
The circumference of, or distance round, any space; the measure of a line round an area
The act of moving or revolving around, or as in a circle or orbit; a revolution; as, the periodical circuit of the earth round the sun
A circuit is a path which begins and ends at the same vertex Note that a circuit does not necessarily have to pass by every vertex or edge, nor is a circuit restricted to passing vertices and edges only once Compare with a cycle
A circuit is a series of places that are visited regularly by a person or group, especially as a part of their job. It's a common problem, the one I'm asked about most when I'm on the lecture circuit
