8.6 - The three-phase wye-connected loads are in parallel across a three-phase supply. The first load draws a current of 20 A at 0.9 power factor leading, and the second load draws a current of 30 A at 0.8 power factor lagging. Calculate the following: a. The transmission line current b. The power factor of the load c. The real power supplied by the source if the line-to-line voltage of the transmission line is 400V
