A torch is simply a circuit containing a battery, a bulb and a switch. The three components are connected in series (one after the other) to form a loop. The switch simply completes the circuit so that power flows from the battery to the bulb.

A torch works by completing an electrical circuit. When the switch is turned on, it allows the battery to supply power to the light bulb, which converts electrical energy into light. By controlling the flow of electricity through the circuit, the torch can be turned on and off as needed.
