1.When you turn on a light bulb, electricity flows trough the filament and as the filament heats up it produces lights

2. Because of the heating effect of electric current, the filament then heats up and becomes red-hot as a result of this it begins to glow, turning light energy into electrical energy

  1. NO

-charge is comerved. Charges moving through the filament produce friction which beats up the filent and pedures light.
