Question

Point out the components of an electric torch and explain how an electric torch works.

Answer 1

The necessary items required to build a torch are wire, cell, and a bulb that lights when the circuit is complete. An electric cell is a source of electricity that is inserted in the torch. The electric cell is connected to the bulb of the torch through a wire. There is a switch present in the wire which when switched on completes the circuit and the bulb glows.
