4) Write down the transformation of energy in torch light.

The transformation of energy in a torch light is as follows:

1) When the torch is turned ON, the chemical energy in the batteries is converted into electrical energy.

2) The electrical energy is converted into heat and light energy. (We feel the torch to be hot after some time and we can see the light energy)

Hope this helped!
