Abalanced y-connected load having an impedance of 60 - j45 ω/φ is connected in parallel with a balanced δ-connected load having an impedance of 90√2∠45° ω/φ. the paralleled loads are fed from a line having an impedance of 2 + j2 ω/φ. the magnitude of the line-to-line voltage of the δ-load is 300 √3 v. a) calculate the magnitude of the phase current in the y-connected load. b) calculate the magnitude of the phase current in the δ-connected load. c) calculate the magnitude of the current in the line feeding the loads. d) calculate the magnitude of the line voltage at the sending end of the line.
