Explanation:
Joule's law of heating states that power of heating generated by an electrical conductor is proportional to the product of its resistance (R) and square of the electric current passing through the conductor with time.
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

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
