Question

Define Joules law of heating ??​

Answer 1

When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. This is known as Joule's law.the principle 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. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.

Answer 2

Answer:

Joule's law of heating states that, when a current 'i ' passes through a conductor of resistance 'r' for time 't' then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.
