A 110V, 4-pole, 50HZ, single-phase induction motor has a main winding impedance Zm-(2+j5) N. The rotor impedance referred to main winding is Z2=(5+j4) ; the auxiliary winding impedance is Za-(7+j5) N, the magnetizing reactance is XM-(j60) 2 The effective turns ratio is a=1.2, a capacitor of 250µF is connected in series with the auxiliary winding. At standstill condition (S=1), find the input current, power factor, voltage across the capacitor, and starting torque in (Nm).
