Average power delivered by the source. 60 Hz d. Reactive power delivered by the source. j12 0 e. Load power factor and power factor angle. 5. [10 pts] The circuit from Problem 4 is redrawn with an added capacitor. What effect does adding the given capacitor have on power consumption (complex, real, and reactive), and the power factor? 50 120 VRMS 185 UF 60 Hz j12 0 6. [10 pts] For problem 4, derive the instantaneous power, p(t), delivered by the source
