1. The problem statement, all variables and given/known data
An unbalanced, star connected load with a neutral connection has resistances of value 2,4,1 in the a,b,c lines, and a resistance of 3 in the neutral.
Find the current flowing in each line and in the neutral

2. Relevant equations
I think:
Va = ZaIa + Zn(Ia+Ib+Ic)
Vb = ZbIb + Zn(Ia+Ib+Ic)
Vc = ZcIc + Zn(Ia+Ib+Ic)

3. The attempt at a solution

.'. Va = 5Ia+3Ib+3Ic
Vb = 7Ib+3Ia+3Ic
Vc = 4Ic+3Ia+3Ib

if this is right so far, i am unsure where to go next! THANK YOU!
