Why is very less quantity of heat energy produced in the connecting wires?
Connecting wires have low resistance to the flow of current. This means, less of the electrical energy is converted to heat energy due to resistance.
The plates of charged condenser are connected by a conducting wire. The quantity of heat produced in the wire is
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.
