1. For Figure 1: The 34 source on the left delivers power to a 30 load via conductors with an impedance of (6+j8) 2 per line. The magnitude of the line-to-line voltages at the source side and at the load side are 120 and 110 kV, respectively. If the power factor of the load is 0.90 lagging, determine (a) the currents (magnitude and angle) and voltages (magnitude and angle) of the 30 load. (Hint: Voltage at the source side and the load side have given magnitude but different angles. Assume the load is Y-connected and use its Van as the reference.)
