Power system analysis lesson homework question anybody can help

Q5. a) A 6 kV rms three-phase power supply is applied to a balanced Y-connected three-phase load consisting of three identical (same) impedances of 48236.870 0. Taking the phase to neutral voltage Van as reference, calculate; (i) The phasor currents in each line. (ii) The total active and reactive power supplied to the load. b) Repeat the problem with the same three-phase impedances arranged in a Delta connection. Take Vab as reference.
