  • 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 ∝ I2t
