Explanation:

Joule effect. ... "Joule's first law" (Joule heating), a physical law expressing the relationship between the heat generated and current flowing through a conductor. Joule's second law states that the internal energy of an ideal gas is independent of its volume and pressure, depending only on its temperature.

Answer:

Joule heating, also known as Ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor produces heat.

A quantitative form of Joule's law is that the heat evolved per second, or the electric power loss, P, equals the current I squared times the resistance R, or P = I^2R. The power P has units of watts, or joules per second, when the current is expressed in amperes and the resistance in ohms.

This equation is the Joule's equation of electrical heating. Joule's law states the amount of heat production in a conductor is : Directly proportional to the square of electric current flowing through it. Is directly proportional to the resistance of the conductor.
