Question

Pls explain joule's law of heating
Fasttttttttt

Answer 1

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.

Answer 2

Joule's Law of Heating. The heat which is produced due to the flow of current within an electric wire, is expressed in unit of Joules. ... The heat generated due to the flow of current is proportional to the time of current flowing, when the electrical resistance and the amount of current is constant.
