Which of these do you think uses less electrical energy - electric bulb or LED?
Ans) LED will use very little electrical energy .In an electric bulb most of the electrical energy gets converted into heat energy and very little light energy is given out . Whereas in LED more light energy is given out as compared to electric bulb and little heat energy is produced.
Could you please check my answer.
