Detailed Solution

According to Joule's law of heating, when a current I flows through a conductor of resistance 'r' over a period of time 't,' the amount of heat generated in the conductor is equal to the square root of the current's current, the resistance's resistance, and the passage of time.
The rate of heat production in a conductor is exactly proportional to the square of the current I and the time t during which the current is passed, according to Joule's law of heating.
$H \propto I^{2} t$
