reactive power

    How do you calculate the complex power phase angle (φ) for reactive power calculations?

    I know you can find reactive power out from the alternative formula below, but using the formula "P(W) = V(V) × I(A) × cos φ", how do you obtain the complex power phase angle (φ) from knowing the Voltage, Power and Current? Alternative formula: Reactive Power=√ (Apparent Power²– True power²)...
