because of the electricity in the battery
you spelt battery rong
Batteries are inserted negative to positive and the battery contains electricity which produces heat and light therefore making the battery makes the torch work
When you cleaned the torch did you also put a fresh, clean battery in the torch and test the bulb to see if tht works as well
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.
That's what it's all about: using the energy from the sunlight. By the way, while there is sunlight, you can store the energy in a battery, and then use it during the night.
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.

my torch does work though...
A mobile 'phone needs a source of energy to power and make it work. A battery provides this energy.
Things that need a battery in order to work, must need Direct Current at some point, if not all, for it to work. eg a hand torch.
The energy wheres Out and becomes a liquid. You can cut open a battery after it Doesent wOrk a see the liquid.
The batteries supply the needed energy, and complete the circuit, allowing the torch to work. (You can see the effect of having a complete circuit, for it to work when you put the batteries in the wrong way. This disconnects the circuit.)
