When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. ... The amount of current, I. the higher the current the larger the amount of heat generated

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 .
