A balanced three-phase source having a line voltage of 208-Vrms is supplying two parallel-connected three-phase loads. The first load is a balanced delta of impedance 21 angle 30° ohms per phase and the second load is a balanced wye of impedance 9 angle -60° ohms per phase. Find the magnitude of the rms line current and the total average power absorbed by the load.
