Complex Imaginary 1-40

[thebard]

I'm just wondering, why does this problem have the wye phase impedances different from the node denotation? Ex: Node A has Zc, B Za, C Zb. Why not just denote them A Za, B Zb, C Zc?

Also, are the equations in the solution correct?

Thanks.

My 1-40 is a power factor question. Maybe post the problem?
