5. A balanced positive-sequence wye- connected 60-Hz three-phase source has line-to-line voltages of VL = 208 V rms. This source is connected to a balanced wye- connected load. Each phase of the load consists of an impedance of 30 + j40 №. Find the line-to-neutral voltage phasors, the line-to-line voltage phasors, the line-current phasors, the power, and the reactive power delivered to the load. Assume that the phase of Van is zero.
