Question

What is joule's law of heating ?? i need appropriate answer...​

Answer 1

According to the joules law of heating,
The heat produced is,

1.directly proportional to the square of current for a given resistance,

2.directly proportional to the resistance for a given current, and

3.directly proportional to the amount of time for which the current flows through the resistor.

Answer 2

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.
