An acb sequence balanced three-phase Y-connected source supplies power to a balanced, three-phase Δ-connected load with an impedance of 12 + j9 Ω/ϕ The source voltage in the b-phase is 240 V. The line impedance is 1 + j1 Ω/ϕ Draw the single phase equivalent circuit for the a-phase and use it to find the current in the a-phase of the load.
