Here's your answer bud :-

Joule’s Law of Heating Effect of Electric Current states that the heat produced in a resistor is directly proportional to the square of current flowing through it, directly proportional to resistance for a given current, and is directly proportional to time for which current flows through the conductor, H ∝ t.
So,
H ∝I^2RT
H = J× I^2Rt (J is the proportionality constant = 1)
H= I^2RT

UPvote and lemme know if that helped:)

Joule's law of heating is a physical law that describes the relationship between the heat generated by an electric current passing through a conductor and the resistance of the conductor. This law is named after the English physicist James Prescott Joule, who first discovered the relationship in the 19th century.

Joule's law of heating can be explained in detail as follows:

The Law
The law states that the heat generated by an electric current passing through a conductor is directly proportional to the resistance of the conductor and the square of the current passing through it. This law can be mathematically expressed as:

H = I2Rt

Where,
H = Heat generated
I = Current passing through the conductor
R = Resistance of the conductor
t = Time for which the current flows through the conductor

Explanation
The law suggests that the heat generated by a conductor is directly proportional to the current passing through it, which means that if the current increases, the heat generated will also increase. Similarly, the heat generated is also directly proportional to the resistance of the conductor, which means that if the resistance increases, the heat generated will also increase.

Additionally, the law states that the heat generated is proportional to the square of the current passing through the conductor. This means that if the current passing through the conductor is doubled, the heat generated will be four times greater.

Applications
Joule's law of heating has several practical applications. It is used to determine the amount of heat generated by electric appliances such as heaters, ovens, and toasters. It is also used to calculate the power dissipation of electronic components such as resistors and transistors.

Conclusion
Joule's law of heating is an important law in physics that describes the relationship between the heat generated by an electric current passing through a conductor and the resistance of the conductor. It has several practical applications and is used in various fields, including electrical engineering and electronics.
