Question

A switch is a simple device that is used:

• A. only to break the circuit
• B. only to give power to the circuit
• C. only to complete the circuit
• D. to either complete or break the circuit

Answer 1

The correct option is D to either complete or break the circuit

A switch is a simple device that is used to either complete or break the circuit.
Current flows through the circuit only when the circuit is complete.
In the circuit, the bulb will glow when the switch is in “ON” position which means the circuit is closed.
When the switch is in “OFF” position which means the circuit is open, the bulb will not glow as shown.
