Joule's Law Calculator

Formula

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

$H = I^2RT$

Where:

$H$ is the heat produced (Joules).
$I$ is the current (Amperes).
$R$ is the resistance (Ohms).
$T$ is the time (Seconds).

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.
