Question

Explain conversion of energy when we switch on an electric bulb.

Answer 1

Answer:

WHEN AN ELECTRIC BULB IS SWITCHED ON THROUGH TAPPING THE SWITCH BOARD, THE MECHANICAL ENERGY IN OUR BODY RELEASES THE ELECTRICAL ENERGY FROM THE CIRCUIT. THE ELECTRICAL ENERGY GETS CONVERTED TO LIGHT ENERGY AND SOMETIMES IT ALSO GETS CONVERTED TO HEAT ENERGY. ALTHOUGH HEAT ENERGY IS PRODUCED IN A VERY MINUTE AMOUNT. (THIS IS ALSO CALLED ENERGY DEGRADATION)
