Question

Explain joules law of heating​

Answer 1

Answer:

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. Directly proportional to the time for which electric current flows through the conductor.

Answer 2

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.

Joule's first law, also known as the Joule–Lenz law,[1] states that the power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the current:

I^{2}R}

Joule heating affects the whole electric conductor, unlike the Peltier effect which transfers heat from one electrical junction to another.
