In a balance three-phase system, the source has an abc-phase sequence and is connected in delta. The line connecting the source to the loads has an impedance of 1+ j2 ohms per phase. There are two loads connected in parallel. Load 1 is connected in wye, and the phase impedance is 4 + j2 ohms. Load 2 is connected in delta, and the phase impedance is 12 + j9 ohms. The phase current Ib1 in the wye load is 16<45 A. . Find the phase voltages of the source and the line currents. Write your values in polar form.
