Power Dissipation Calculator

The equations below solve for power based on current and voltage, voltage and resistance, or current and resistance.

Inputs
Connection Type:
Voltage:
R - {{ key + 1}}
Dissipation: {{resistor.dissipation}} watts

Equations

$$P = I X V$$

$$P = V2/ R$$

$$P = I2 X R$$

Application

This calculator helps determine power dissipation from voltage, current, and resistance.
