15. The main and auxiliary windings of a hypothetical 130-V, 60-Hz, split-phase motor have the following locked-rotor parameters: Rmw = 2.3 Ohms, Xmw = 3.0 Ohms, Raw = 9.25 Ohms, and Xaw = 8.2 Ohms. The motor is connected to a 130-V, 50-Hz system. Determine the capacitance, in microfarad, required in series with the auxiliary winding in order to obtain a 86 degrees phase displacement between the currents in the two windings
