A balanced Y-connected load having an impedance of 60 - j45Ω/ϕis connected in parallel with a balanced Δ-connected load having animpedance of 90√2∠45∘ Ω/ϕ. The paralleled loads are fed from a linehaving an impedance of 2 + j2Ω/ϕ. The magnitude of the line-to-linevoltage of the Δ-load is 200√3 V.
Part A: Calculate the magnitude of the phase current in theY-connected load.
Part B: Calculate the magnitude of the phase current in theΔ-connected load.
Part C: Calculate the magnitude of the current in the linefeeding the loads.
Part D: Calculate the magnitude of the line voltage at thesending end of the line.
