The complex power associated with each phase of a balanced load is 144 + j192 kVA. The line voltage at the terminals of the load is 2450 V. A balanced bank of delta- connected capacitors is connected in parallel with the load. The circuit is operating at a frequency of 60 Hz. The capacitors are adjusted so that the magnitude of the line current feeding the parallel combination of the load and capacitor bank is at its minimum.
1. What is the size of each capacitor in microfarads?
2. Repeat (a) for wye connected capacitors.
3. What is the magnitude of the line current?
