Question

write down joule's law of heating effect of electric current?

Answer 1

Joule's Law of Heating. Theheat which is produced due to the flow of current within an electric wire, is expressed in unit of Joules. ... The heatgenerated due to the flow of current is proportional to the time of current flowing, when the electrical resistance and the amount of current is constant.

Answer 2

Hi...

Here's your ans :-

JOULE'S LAW OF HEATING EFFECT OF ELECTRICCURRENT ------

When a current flows through a conductor, the quantity of heat produce in it is directly proportional to :-

(1) the square of the current

(2) the resistance of the conductor

(3) the time for which the current flows.

Hope it helps
