Question

You have seen
that the heating effects of current can be put to good use. can you think of situations where this effects results in wastage of energy?

Answer 1

as u can see heating effect is quite helpful for us but they also consumes large amount of energy...

a room heater consumes nearly 1500 watt of energy and also large amount of energy wastage occurs hence it results in energy wastage...

hope u find this useful..

Answer 2

Answer:

Yes, when electric current passes through long conductors, a portion of energy is wasted in the form of heat. Also,

in case of an incandescent lamp, only a part of electricity is converted into light and the rest is wasted as heat,

which is unwanted.
