Real Power (P) - Watts

Reactive Power (Q) - VAR

Apparent Power (S)

-- VA

Power Factor

Phase Angle (θ)

--°

Reactive Factor

Real Power (P): Measured in Watts (W), represents useful work
Reactive Power (Q): Measured in Volt-Amps Reactive (VAR), represents energy stored and returned
Apparent Power (S): Measured in Volt-Amps (VA), the vector sum of P and Q
Power Factor (PF): Ratio of real power to apparent power (P/S)
Phase Angle (θ): Angle between voltage and current waveforms
Power Triangle Formula: S² = P² + Q²
