The following three-phase circuit is symmetrical, with line voltage 220 V, 60 Hz, direct phase sequence, isolated neutral and the value of the impedances of the loads in the three phases are:

Zan = 10 ohms

Zbn = -10j ohm

Zcn = -10j Ohm

Find:
a) Phase voltages on the load;
b) Line and phase currents;
c) The power supplied to the load.

Consider the phase voltage in the reference
(Va voltage angle equal to 0)
