Real and Reactive Power

Computes real power (W) and reactive power (VAR) from voltage, current, and phase angle. Supports both single-phase and three-phase configurations.

Inputs

1 = Single phase, 2 = Three phase

RMS voltage in volts (source label shows Cyrillic М — assumed volts)

RMS current in amps

Phase angle between voltage and current in degrees

Results

Real Power0.000e+0WReal (active) power in watts — n=1 for single phase, n=√3 for three phase
Reactive Power0.000e+0VARReactive power in volt-amperes reactive (source labels unit as watts — that is a source bug)
