(a) Find both wattmeter readings in Fig. 12.39 if VA = 100/0 V rms, VB = 50/90 V rms, ZA

Chapter 12, Problem 39

(choose chapter or problem)

(a) Find both wattmeter readings in Fig. 12.39 if \(\mathbf{V}_A=100 \angle 0^{\circ}\mathrm{\ V\ }\mathrm{rms}\), \(\mathbf{V}_B=50 \angle 90^{\circ}\mathrm{\ V\ }\mathrm{rms}\), \(\mathbf{Z}_A=10-j10\ \Omega\), \(\mathbf{Z}_B=8+j6\ \Omega\), and \(\mathbf{Z}_C=30+j10\ \Omega\). (b) Is the sum of these readings equal to the total power taken by the three loads? Verify your answer with an appropriate PSpice simulation.
