Question

describe the joule law of heating​

Answer 1

Explanation:

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

Answer 2

When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. How much heat is generated during current flowing through a wire and on what conditions and parameters do the heat generation depend? James Prescott Joule an English physicist, coined a formula which explains this phenomenon accurately. This is known as Joule’s law.
