Three condensers, each having a capacity of 75 microfarads are connected in star to a 440 volts, 3-phase, 50 cycles supply. Calculate the capacitance of each of the three condensers so that when they are connected in delta to the same supply and the line current remains the same. 30 microF 20 microF 28 microF 25 microF
