Power Dissipation

Estimate how much heat or energy a component dissipates. Perfect for resistor sizing, LED design, and safe load calculations.

Power Dissipation Calculator

Enter any two known values — voltage (V), current (A), or resistance (Ω). The calculator will determine the missing variable and compute total power.

Manage Heat, Protect Components.

Confirm that your resistors, LEDs, and transistors are within safe thermal limits — then use AOEngineering’s tools to build with precision and reliability.
