Joule’s law

Joule’s law
The Heat produced by an electric current flowing through a conductor is equal to the product of the square of the current passed, the resistance of the conductor and time for which current is passed.
i.e. Heat generated H = I2Rt
Here, I- is the intensity of current in Ampere.
R-is the resistance of the conductor in ohm.
t-is the time taken by the current in seconds.
