An abc-sequence, balanced 3-ph supply with a line voltage of 400 V supplies two balanced 3-phase loads that are connected in parallel. The first load is Y-connected and has an impedance of 30 + j40 Q per phase. The second load is A-connected and has an impedance of 60 - j45 Q. The line has an impedance of 2 + j4 Q. Taking the phase voltage EA as reference, determine the line currents, the phase currents per load, and the total complex power supplied by the source. I

Kindly show your solution please. Thank you in advance

An abc-sequence, balanced 3-ph supply with a line voltage of 400 V supplies two balanced 3-phase loads that are
connected in parallel. The first load is Y-connected and has an impedance of 30 + j40 Q per phase. The second load
is A-connected and has an impedance of 60 - j45 Q. The line has an impedance of 2 + j4 Q. Taking the phase
voltage EA as reference, determine the line currents, the phase currents per load, and the total complex power
supplied by the source.
