Chapter 12.4, Problem 7P

Each phase of a balanced three-phase ∆-connected load consists of a 200 mH inductor in series with the parallel combination of a 5 μF capacitor and a 200 Ω resistance. Assume zero line resistance and a phase voltage of 200 V at ω = 400 rad/s. Find (a) the phase current; (b) the line current; (c) the total power absorbed by the load.
