State Joules law of heating.

1.	State Joules law of heating.
Answer» Acc to this law, heat is directly proportional to the product of square of current, resistance and time. 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. Joule law of heating says that the heat is directly proportional to the temperature,resistance and the square of the current
