The working principle of torch is same as a normal circuit .
When the cells are put into the torch and when it comes in contact with the conductor (metal)
the flow of current created by the cells starts flowing .
When the current reaches to the bulb present inside the torch , the filament ( made up of tungsten ) get heated and starts glowing .
The concave mirror present in front of the bulb
helps to focus all the ray of light at a particular place as it is a coverging mirror .
This is how a torch works !!!
I hope this will help you !!!
