A balanced bank of delta-connected capacitors is connected in parallel with the load which complex power associated with each phase of a balanced load is 146+191j kVA. The effect is to place a capacitor in parallel with the load in each phase. The line voltage at the terminals of the load thus remains at 2460 V The circuit is operating at a frequency of 65 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. Part A) What is the size of each capacitor? Express your answer in microfarads to three significant figures.
Part B )What is the size of each capacitor if they are wye-connected capacitors? Express your answer in microfarads to three significant figures.
Part C) What is the magnitude of the line current? Express your answer in amperes to three significant figures.
