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 .
