AC Power
P = V × I × cos(θ) for single-phase. P = √3 × V × I × cos(θ) for three-phase. Enter voltage, current, and power factor angle to solve for power, or rearrange to solve for voltage or current.
Inputs
RMS voltage of the AC system
RMS current of the AC system
Phase angle between voltage and current in degrees
Enter 1 for single-phase or 3 for three-phase
