Question

What is heating effect of current?

Answer 1

Heya Bro.
---------------

Here is Your Ans. -------->

The heating caused due the passing of electric currentthrough any material is called the heating effect of electric current. Eg, elecric heater.
You can see this effect even in incandesent lamp. This is why they radiate heat alongwithlight and thus consume relatively more electricity than CFLs.

Hope it Helps you ☺

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 .
