In Problem 11.5, a balanced -connected load with Z = 20 45 resulted in line

In Problem 11.5, a balanced Δ-connected load with Z = 20 ∠ 45° Ω resulted in line currents 8.65 A for line voltages 100 V, both maximum values. Find the readings of two wattmeters used to measure the total average power.

Data from problem 11.5

A three-phase, ABC system, with an effective voltage 70.7 V, has a balanced Δ-connected load with impedances 20 ∠ 45° Ω. Obtain the line currents and draw the voltage-current phasor diagram.
