No Shortcut, No skipping, and detailed as possible 6. FINAL ANSWERS must be rounded up to three decimal places   PROBLEM: • An abc-phase sequence three-phase balanced wye-connected source supplies a balanced delta-connected load. The impedance per phase of the delta load is 10+j8 Ω. If the line impedance is zero and the line current in a phase is known to be la=28.10<-28.66° Arms, find the load voltage Vab.
