Question

What happens when the switch in a circuit is turned OFF (open circuit)?

Options

• No current flows and connected devices stop working

• Only AC devices continue to operate

• Current continues to flow but reverses direction

• Current flows at double its normal value

Answer 1

A switch is used to make (close) or break (open) the circuit loop. When the switch is OFF, the circuit is open, no current flows, and devices stop working. When the switch is ON, the circuit is closed and current flows.
