Question

can you think of a instance where the heating effect of electric current causes wastage of energy

Answer 1

hey mate

here is your answer

the best example where heating effect of electric current causes wastage of energy is fluorescent bulbs that we use in our houses.
it converts 30% of the total electricity supply to the bulb into to heat energy. thus, 30% of energy gets dissipated or degraded

Answer 2

When current passes in a conductor, heat energy generated in the conductor. The main factor of heating are :

• The time, t for which current flows. The longer the time, the more considerable the amount of heat produced

• The resistance of the conductor. A higher resistance produces more heat.

• The amount of current through the conductor, the higher the flow, the more significant the amount of heat generated.

Therefore the heating impact created by an electric current I ,resistance R for a time, t is given by$H = I^{2} Rt$. This equation is called Joule’s comparison of electrical heating.
