An electric circuit is a path along which current can flow. This is a rather broad definition because under the right conditions almost any object can conduct electricity. For example, air is usually considered an insulator (that is, a substance that...

An electrical circuit controls the flow of electricity. It is composed of various components, depending on its purpose. The most common components in a circuit are switches, capacitors, resistors, inductors, and potentiometers. Adding vacuum tubes...

An electric circuit is a system of conducting elements designed to control the path of electric current for a particular purpose. Circuits consist of sources of electric energy, like generators and batteries; elements that transform, dissipate, or...

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...

An electrical network is an interconnection of electrical elements such as resistors, inductors, capacitors, transmission lines, voltage sources, current sources, and switches. An electrical circuit is a network that has a closed loop, giving a return...
