When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. This is known as Joule's law.the principle that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.

Answer:
heating of a conductor due to the flow of electric current through it is known as Joule's law of heating. Heat generated H=i2Rt. 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.
