Answer
live wire
Reason — By placing the switch in the live wire, it effectively breaks or completes the circuit when operated. This ensures that when the switch is turned off, the live wire is disconnected, preventing the flow of current through the circuit, thus effectively cutting off power to the connected device or load.
