Calculate Heat Produced





Formula

The formula to calculate the heat produced (H) according to Joule's Law is:

\[ H = I^2RT \]

Where:

Example

Let's say the current is 2 Amperes, the resistance is 5 Ohms, and the time is 10 seconds. Using the formula:

\[ H = (2)^2 \times 5 \times 10 \]

We get:

\[ H = 4 \times 5 \times 10 = 200 \]

So, the heat produced (\( H \)) is 200 Joules.

What is Joule's Law?

Joule's Law, named after English physicist James Prescott Joule, is a fundamental principle in the field of electricity that states the amount of heat produced by a direct current is directly proportional to the square of the current, the resistance it encounters, and the time for which it flows. This law is mathematically represented as \( H = I^2RT \), where \( H \) is the heat produced, \( I \) is the current, \( R \) is the resistance, and \( T \) is the time.
