Question

Name any four components of an electric circuit. Give their electrical symbols.

Accepted Answer

Four components of an electric circuit are given below:

Electric cell: An electric cell acts as a source of energy for an electric circuit. It consists of two terminals that maintains the potential difference across the circuit. The current always flows from the positive terminal of the cell to the negative terminal of the cell.

Electric bulb: An electric bulb consists of a filament made of tungsten which heats up and glows when a current is passed through it.

Switch: A switch is a device that controls the flow of current through an electric circuit. It makes or breaks an electric circuit.

Resistor: Resistance is the property of a wire by virtue of which it opposes the flow of current through it. The device which opposes the current to pass through it freely is known as resistor.
