Joule's Law Of Heating and Joule's First Law - Physics - BYJU'S
Joule’s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy. The English physicist James Prescott discovered that the amount of heat per second that develops in a current-carrying conductor is proportional to the electrical resistance of the wire and the square of the current.
Joule's law | Definition, Calculation & Application - Magnetism
Joule’s law states that the heat generated by a current flowing through a conductor is directly proportional to the square of the current, the resistance of the conductor, and the time for which the current flows.
