Explanation:
Joule law of heating...
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.

What is 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. Now the mathematical representation and explanation of Joule’s law is given in the following manner.
The amount of heat produced in a current conducting wire, is proportional to the square of the amount of current that is flowing through the wire, when the electrical resistance of the wire and the time of current flowing are constant.
The amount of heat produced is proportional to the electrical resistance of the wire when the current in the wire and the time of current flowing are constant.
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.
