Question

what is meant by joule law?​

Answer 1

Joule's law of heating States that
Heat produced in the resistor is directly proportional to :
1. Square of the current flowing through the circuit.
2. Resistance of the circuit.
3. Time for which the current flows through the resistor.

Answer 2

Joule's law is stated and explained below.

• The joule's law states that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current.
• It can be explained as when more resistance is present in a conductor, more heat is going to be produced.
• It is a fact that the resistance present produces more friction which will obstruct the current flowing.
