Question 2

Choose the incorrect statement.

(a) A switch is the source of electric current in a circuit.

(b) A switch help to complete or break the circuit.

(c) A switch helps us to use electricity as per our requirement.

(d) When the switch is open there is an air gap between its terminals.

Answer 1

Option (a) is the correct answer.

A switch is an electrical device used to make or break an electric circuit. It controls the flow of current in a circuit by ON/OFF mechanism. Hence it is not a source of electric current in a circuit. An electric cell or battery acts as a source in a circuit.

When the electric switch is in open position, there will be an air gap between two terminals so that it breaks the circuit.
