In each of the three phases in a balanced delta- connected load is composed of a 10mF capacitor in parellel with a series-connected 470 ohm resistor and 4mH inductor combination, assume a phase voltage of 400 V at 50 Hz. a) calculate the phase current b) the line current. c) the line voltage . d) the power factor at whic the source operates e) the total power delivered to the load.
