Answer:
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.
