Extracted text: 11.15 An acb sequence balanced three-phase Y-connected source supplies power to a balanced, three-phase A- connected load with an impedance of 12 + j9 2/4. The source voltage in the b-phase is 240/-50° V. The line impedance is 1 + jl 2/4. Draw the single phase equivalent circuit for the a-phase and use it to find the current in the a-phase of the load.
