A dedicated calculator simplifies this process, allowing users to quickly and accurately compute the heat generated by resistors. In this article, we will provide a step-by-step guide on how to use the resistor heat calculator, including the formula, examples, FAQs, and a working for the calculator.
How to Use
Using the resistor heat calculator is straightforward. Enter the values for voltage (V), current (I), and resistance (R) in the designated input fields. Click the “Calculate” button, and the calculator will instantly provide the heat dissipated by the resistor.
Formula
The formula for calculating heat (H) generated by a resistor is given by:
H=I2×R
where:
- H is the heat generated (in watts),
- I is the current passing through the resistor (in amperes),
- R is the resistance of the resistor (in ohms).
Example Solve
Let’s consider an example where a resistor has a resistance of 100 ohms, and a current of 0.5 amperes is passing through it.
So, the heat generated by the resistor is 25 watts.
