Question: A balanced Y-connected load with 2 + j3 /ph (L-N) is connected in parallel with a balanced -connected load with 9 + j12 /ph (L-L).

A balanced Y-connected load with 2 + j3 Ω/ph (L-N) is connected in parallel with a balanced Δ-connected load with 9 + j12 Ω/ph (L-L). Determine the combined total equivalent Y-connected impedance value per phase. If these loads were powered by a Y-connected 480-V_LL generator, determine the current drawn from the generator lines.
