Question

A device is used to break the flow of current in a circuit.

Answer 1

1. An electric device that is used to make a circuit work or to stop is called a switch.
2. If a switch is off, it means that the circuit is closed and the current flows.
3. If a switch is on, it means that the circuit is open and the current does not flow.

Hence, a device used to break the flow of current in a circuit is called a switch.
