Power Triangle Calculator

See how active and reactive power combine into apparent power and phase angle.

01 / Inputs

Power values

P is nonnegative. Positive Q indicates lagging reactive power; negative Q indicates leading reactive power.

02 / Result

Power triangle

Waiting for input

Enter P and Q to calculate apparent power, power factor, and phase angle.

Method and boundaries

S = √(P² + Q²), power factor = P/S, and φ = atan2(Q, P). Positive Q represents lagging reactive power; negative Q represents leading reactive power.

At zero apparent power, power factor and angle are undefined. Electrical code compliance and equipment suitability are not evaluated. Source SRC-002 · model 1.0.0 · dataset user-input-v1.
