a) Find the reading of each wattmeter in the circuit shown in Fig. P11.52 if and b) Show

Chapter 11, Problem 11.52

(choose chapter or problem)

a) Find the reading of each wattmeter in the circuit shown in Fig. P11.52 if \(Z_{\mathrm{A}}=20 \angle 30^{\circ} \ \Omega\), \(Z_{\mathrm{B}}=60 \angle 0^{\circ} \ \Omega\), and \(Z_{\mathrm{C}}=40 \angle-30^{\circ} \ \Omega\).

b) Show that the sum of the wattmeter readings equals the total average power delivered to the unbalanced three-phase load.
