Jabarkan Disipasi daya dari Résistor dalam bahasa sunda

The power dissipated by a resistor is the voltage across the resistor multiplied by the current through the resistor:

All three equations are equivalent.  The first is derived from Joule's law, and other two are derived from that by Ohm's Law.

The total amount of héat energy reléased is the integral of the power over time:

If the average power dissipated exceeds the power rating of the resistor, then the resistor will first depart from its nominal resistance, and will then be destroyed by overhéating.
