**11.14** In a balanced three-phase system, the abc-phase-sequence source is delta-connected and \( V_{ab} = 120/\angle 30^\circ \, \text{V rms} \). The load consists of two balanced wyes with phase impedances of \( 10 + j1 \, \Omega \) and \( 20 + j5 \, \Omega \). If the line impedance is zero, find the line currents and the load phase voltage.
**11.15** An abc-phase-sequence three-phase balanced wye-connected 60-Hz source supplies a balanced delta-connected load. The phase impedance in the load consists of a 20-\(\Omega\) resistor in series with a 50-mH inductor, and the phase voltage at the source is \( V_{an} = 120/\angle 20^\circ \, \text{V rms} \). If the line impedance is zero, find the line currents in the system.
**11.16** An abc-phase-sequence three-phase balanced wye-connected source supplies power to a balanced wye-connected load. The impedance per phase in the load is \( 14 + j12 \, \Omega \). If the source voltage for the a phase is \( V_{an} = 120/\angle 80^\circ \, \text{V rms} \), and the line impedance is zero, find the phase currents in the wye-connected source.
**11.17** An abc-sequence balanced three-phase wye-connected source supplies power to a balanced wye-connected load. The line impedance per phase is \( 1 + j5 \, \Omega \), and the load impedance per phase is \( 25 + j25 \, \Omega \). If the source line voltage \( V_{ab} = 208/\angle 0^\circ \, \text{V rms} \), find the line currents.
**11.18** An abc-sequence set of voltages feeds a balanced three-phase wye–wye system. If the line current in the a phase is \( 16.78/\angle 20.98^\circ \, \text{A rms} \), the line impedance is \( 1.2 + j1.8 \, \Omega \), and the input voltage \( V_{ab
