A three-phase 400 V (line) 50 Hz supply is connected to unbalanced loads in star configuration. The unbalanced line currents are given as: la: 46.2 + j0 b: -11.55-j20 Ic: -7.7 + j13.3 Assuming that the phase voltage, Va, has a phase angle of 0 degrees and that the line impedance is negligible, calculate: (i) The impedance of the load in phase b. (ii) The symmetrical components of line currents,,, and /₂.
