Question

Heating effects of electric current????

Answer 1

HEY MATE ⚛⚛⚛⚛⚛⚛

HERE IS YOUR ANSWER

When an electric current is passed through a conductor , the conductor becomes hot after sometime and produces HEAT . This happens due to the conversion of some amount of ELECTRIC energy passing through the conductor into HEAT energy .
The effect of electric current is called HEATING EFFECT OF ELECTRIC CURRENT .


THANKS FOR ASKING ✌✌

Answer 2

Heating effect of current

The amount of heat produced by a current depends on these factors :

(i) The amount of heat is directly proportional to the square of current flowing through the conductor.

(ii) It is directly proportional to the resistance of the conductor.

(iii) It is also directly proportional to the time the current takes to flow.

• H = heat produced .

• I = current .

• R = resistance .

• T = time .

H ∝ I²

H ∝ R

H ∝ T

Thus H ∝ I²RT

= > H = I²RT

This is also called Joule's Law of heating .
