A three-phase, four-wire system operating with a 208-V line voltage is shown in Fig. 12.71. The source voltages are balanced. The power absorbed by the resistive wyeconnected load is measured by the three-wattmeter method. Calculate:
(a) The voltage to neutral
(b) The currents I1, I2, I3, and In
(c) The readings of the wattmeters
(d) The total power absorbed by the load
