    I have a Y source with a delta load, and I need to find voltage, current, and complex power delivered to the load. However, the Y to delta with line impedance between is throwing me for a loop.

    To find the voltage across any leg of the Delta, I need to solve for the current through the line impedance and the sum of the currents through the Delta, on a per phase basis as per the instructor.

    My initial thought is to convert the load to Y, solve voltage and current there, and convert those to delta currents and voltages.

    Is that the best way to do this?

    Sounds reasonable. A Y-Y is the easiest to determine the single-phase equivalent circuit for.
