Karan is creating a simple electric circuit. Which of the following material should he use to create the electric switch?

A switch is a device that either completes or breaks the circuit.
The electric switch should be made up of a conductor so the electric current can flow through it when it is in the ON position.

Therefore, we can use a paper clip as an electric switch. To break the electric circuit, we can simply lift and move the paper clip away from the wire of the electric circuit.
