Question

Choose the correct statement.

• A. A switch causes the change in direction of current in a circuit.
• B. A switch is used to make or break a circuit.
• C. A switch can increase the amount of current flowing in a circuit.
• D. A switch can decrease the amount of current flowing in a circuit.

Answer 1

The correct option is B A switch is used to make or break a circuit.

A switch is an electrical component that can make or break an electrical circuit. When the switch is 'ON', the circuit is closed, providing a path for the electric current to flow.

On the other hand, when the switch is 'OFF', the circuit is open, breaking the path of the flow of current.

A switch can neither change the direction of current, nor increase or decrease the current flowing through a circuit.
