Answer: Joule's law of heating states that , "The heat produced in a resistor is directly proportional to (1) square of current (I^2) (2) resistance of the resistor (R) and (3) time for which the current flows through the resistor .
and also
Joule's first law" (Joule heating), a physical law expressing the relationship between the heat generated and current flowing through a conductor. Joule's second law states that the internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature

Answer:Joule's law of heating states that the power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the electric current passing through the conductor.
Or we can say
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.
