역률 계산기

Power factor is the ratio of real power absorbed by the load to the apparent power flowing in the circuit and is represented as a number in the range of -1 to 1.

역률 (cos φ) Equation

cosθ = P/S

θ = arctan(Q/P)

Q = √(P-S)

P = Real Power(W)、S = Apparent Power(VA)、Q = Reactive Power(var)、cosθ = 역률 (cos φ)、θ = Phase Angle
