Question

answer in brief what is joules law of heating
with formula and application​

Answer 1

Answer:

Joule's law of heating states that when a current 'i ' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time

Answer 2

Explanation:

When an electric current passes through a conductor for some time, the conductor gets heated up. Thus heating of a conductor due to the flow of electric current through it is known as Joule's law of heating.

Heat generated H=i

2

Rt

where i is the amount of current flowing though the conductor, R is the resistance of conductor and t is the time for which the current has flown.
