5 A three-phase source with a line voltage of 45 kV rms is connected to two balanced loads. The wye-connected load has Z=10j20 2 and the delta load has a branch imped- ance of 50 2. The connecting line have an impedance of 22. Determine the power delivered to the loads and the power lost in the wires. HHELP!!!!! Don't we have to lag 30 degrees to change V to phase voltage?
