The conducting path consisting source, load, switch connected by the conducting wire through which current can flow is called an electric circuit. Diagram of it is given below:
Electric circuit, path for transmitting electric current. An electric circuit includes a device that gives energy to the charged particles constituting the current, such as a battery or a generator; devices that use current, such as lamps, electric motors, or computers; and the connecting wires or transmission lines. circuit diagram (also known as an electrical diagram, elementary diagram, or electronic schematic) is a simplified conventional graphical representation of an electrical circuit. ... Arrangement of the components interconnections on the diagram does not correspond to their physical locations in the finished device.
