the switch in a torch allows the circuit in the torch to be completed
torch
The conducting path of a torch is a simple circuit: Battery to switch, switch to bulb, bulb back to battery. Provided the switch is on, and there are no breaks in the circuit wiring (and the bulb is good), the torch should work.
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.

Inside a torch ther is a bulb a cell and a swith. with some wires connecting them. it is a simple series circuit.
Torch equals flashlight. Battery negative connected to case switched to bulbs outside. Positive connected to the lamps bottom. Called a series circuit.
It breaks the circuit and when it's removed the circuit is complete so electricity can flow.
the answer is 3 hours for the limitation as the chemicals in the batteries produce a current of electricity
In a torch (flashlight), the current passes from the positive terminal, through the bulb, and returns back in the negative terminals, making a complete circuit. When the switch is moved to the on position, a metal piece inside the case touches the positive terminals of the battery, the circuit is completed, and the torch turns on. Move the switch to the off position, the metal piece no longer touches the positive terminals of the battery, and the torch turns off.
If you know what the material is you can determine whether the material is a normal conductor of electricity by reference. If not try completing a circuit with torch battery(ies), a bulb from the torch, some wire and see if the bulb lights up. If so the material in the circuit conducts electricity.
Well don't ask me, i don't know how it works. Why don't you ask yourself that question? huh?
