WebBy measuring the voltage and current in an AC circuit and utilizing the following equation Z =V /I Z = V / I We can obtain the magnitude of circuit impedance. However, it is often desirable to separate impedance into resistive and reactive components. WebThe three different types of power in AC circuits are as follows: S = apparent power, measured in Volt-Amps (VA) P = true power, measured in Watts (W) Q = reactive power, measured in Volt-Amps reactive (VAR) Explain the names of each of these power types. Why are they called “apparent,” “true,” and “reactive”? Question 19
