At temperatures above 70°C, the resistor is derated using the electrical stress ratio. The recommended value is 80% for fixed resistors and 75% for variable resistors. The values at different temperatures are provided by the derating curves.
WitrynaOhm’s Law V = I × R and the Power Equation P = I × V A simple use of these is finding the power rating required for resistors. In this case, enter any two of the following values: the voltage across the resistor, the current through the resistor, or its resistance in ohms to find the power dissipation in watts.
