13 Circuits II

Referring to the balanced load represented in Fig. 12.33, if it is connected to a three-wire balanced source operating at 50 Hz such that VAN = 115 V, (a) determinethe power factor of the load if the capacitor is omitted; (b) determine the value of capacitance C that will achieve a unity power factor for the total load
