Abalanced y -connected load having an impedance of 92+j21ω/ϕ is connected in parallel with a balanced δ -connected load having an impedance of 150∠ 0 ∘ ω/ϕ . the paralleled loads are fed from a line having an impedance of j1ω/ϕ . the magnitude of the line-to-line voltage of the δ -load is 8150 v .

a. calculate the magnitude of the current in the line feeding the loads.
b. calculate the magnitude of the phase current in the y- connected load.
c. calculate the magnitude of the phase current in the delta-connected load.
d. calculate the magnitude of the line voltage at the sending end of the line.
