Remember, apparent power can be found from the product of the RMS voltage and current magnitudes for any complex impedance, and θ is the same as the impedance angle (i.e., the voltage angle...Remember, apparent power can be found from the product of the RMS voltage and current magnitudes for any complex impedance, and θ is the same as the impedance angle (i.e., the voltage angle minus the current angle). As we are often interested in the true power, it is worth noting that a rearrangement of Equation ??? shows that the ratio of true power to apparent power is the cosine of the impedance angle, P/S=cosθ.
