Homework Equations
Vab = Van*root[3] angle 30 degrees
Iab = Vab/Z
Ia = Iab*root[3] angle -30 degrees
The Attempt at a Solution
Load impedance = 18 + j15 = 23.43 angle 39.8
Vab = root[3]*100 angle 30 degrees = 173.21 angle 30 degrees
Iab = 173.21<30/23.43<39.8 = 7.39<-9.8
Ia = 7.39<-9.8 * root [3]<30 = 12.80<-39.8
