4. A balanced 3-6 abc (positive) sequence Y-connected source with 120 Vrms/ has a Y-connected load. The load impedance is 20 +j10 2/6 and the line impedance is 1 + j1 92/4. a) Find the: (i) line current, (ii) phase voltage at the load and (iii) line voltage at the load (a-phase only) b) Repeat part a) if the same load is connected in a A instead of a Y. For (ii) find the phase current in the load. c) Find the complex power S in the a-phase of the load for both parts a) and b). [I and V all rms: a) 5.14-27.7°, 113.2/-1.1°, 196/28.9°, b) 13.6/-29.5°, 7.9/0.5°, 175.9/27.1°, c) 512.5+j256.2, 1237.8+j618.9 VA]
