Question

State joule's law of heating and write it's mathematical expression. ​

Answer 1

Answer:

Joule's law states the amount of heatproduction in a conductor is : Directly proportional to the square of electric current flowing through it. Is directly proportional to the resistance of the conductor. Directly proportional to the time for which electric current flows through the conductor.

formula is Q = I^2 R T

Answer 2

Answer:

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.
