In a Three-phase circuit with a star generator and charge, we have the following canceled voltages in a positive sequence: Van = 110, (Vbn and Vcn are determined with the data presented).

The Charge of ZA = 22Ohms
The Impedance of line Zla is worthless
The Impedance of generator Zga is worthless
The Neutral Impedance Z0 is worthless
All Impedances are balanced

***Picture of the Circuit is attached.***

Find the currents for the Three-phase line: laA, lbB and lcC:

a) laA = 5
   lbB = 5e^120j
   lcC = 5e^-120j

b) laA = 5e^-120j
   lbB = 5e^120j
   lcC = 5e^0j

c) laA = 5
   lbB = 5e^-120j
   lcC = 5e^120j

d) laA = 5e^120j
   lbB = 5e^-120j
   lcC = 5e^0j

Solution

line current magnitude =110/22=5

and these are in same direction as positive sequence so option c is correct one
