$\huge \mathbb\fcolorbox{black}{palevioletred}{Answer♡}$

Sir James Prescott Joule formulated Joules law. It establishes a relationship between heat, voltage, current, and time. When an electric current passes through a circuit or a conductor, heat is produced.

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.
