Electric circuit and circuit diagram:-

• A closed-loop path which a current takes is called an electric circuit.

• Representation of an electric circuit through symbols is called a circuit diagram.

Answer 2

Answer:

$electric \: circuit$

A circuit diagram is a graphical representation of an electrical circuit. A schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations while a pictorial circuit diagram uses simple images of components. Unlike a block diagram or layout diagram, a circuit diagram shows the actual electrical connections.

Before talking about a circuit diagram, let us recall circuits. An electrical circuit is a device which provides the complete path for current to flow. A circuit consists of three basic things to function:

A source of voltage

A conductive path which facilitates the movement of charges

A resistor (say, a light bulb) which requires electricity to do work
