Q. A balanced wye-connected load with a per-phase impedance of 4 + j3 is supplied by a 173-V, 60-Hz three-phase source.
(a) Find the line current, the power factor, the total volt-amperes, the real power, and the reactive power absorbed by the load.
(b) Sketch the phasor diagram showing all the voltages and currents, with ¯VAB as the reference.
(c) If the star point of the load is connected to the system neutral through an ammeter, what would the meter read?
