Joule's Law of Heating relates the heat generated in a conductor to the current passing through it, the resistance of the conductor, and the time for which the current flows. It can be expressed mathematically as:

H = I²Rt

Where:
- H is the heat energy produced in Joules (J)
- I is the current flowing through the conductor in Amperes (A)
- R is the resistance of the conductor in Ohms (Ω)
- t is the time for which the current flows in seconds (s)

Explanation:
1. Joule's Law of Heating:
Joule's Law of Heating states that the heat produced in a conductor is directly proportional to the square of the current passing through it, the resistance of the conductor, and the time for which the current flows.

2. Heat Energy:
The heat energy produced in a conductor is denoted by the symbol H and is measured in Joules (J). It represents the amount of thermal energy generated by the flow of electric current.

3. Current:
The current flowing through a conductor is denoted by the symbol I and is measured in Amperes (A). It represents the rate of flow of electric charge in a circuit.

4. Resistance:
The resistance of a conductor is denoted by the symbol R and is measured in Ohms (Ω). It represents the opposition offered by the conductor to the flow of electric current.

5. Time:
The time for which the current flows through a conductor is denoted by the symbol t and is measured in seconds (s). It represents the duration of the current flow.

6. The Equation:
The equation H = I²Rt represents Joule's Law of Heating. It shows that the heat energy produced in a conductor is directly proportional to the square of the current, the resistance, and the time.

7. Interpretation:
According to Joule's Law of Heating, if the current passing through a conductor increases, the heat generated in the conductor also increases. Similarly, an increase in resistance or time will result in an increase in heat energy produced.

8. Application:
Joule's Law of Heating is utilized in various electrical devices such as electric heaters, toasters, and electric stoves. It helps in calculating the amount of heat generated and ensures the safe and efficient operation of these devices.

In conclusion, Joule's Law of Heating provides a mathematical relationship between the heat energy produced in a conductor, the current passing through it, the resistance of the conductor, and the time for which the current flows. It is an important principle in understanding and designing electrical circuits and is widely used in various electrical applications.
