[20%] A 1-phase AC induction motor has main winding and auxiliary winding. The specification of the main winding is R1 = 20 ohm and L1 = 60 mH, Meanwhile, R2 = 20 ohm, L2 = 60 mH, and C2 = 100 uF in the auxiliary winding. If the motor is connected to grid voltage (PLN): a. Calculate the amplitude of the current flowing in the main winding and in the auxiliary winding. b. Calculate the phase angle of the current flowing in the main winding and in the auxiliary winding C. Draw v(t) and i(t) of the main and auxiliary winding in a single graph. Based on the graph, show the phase difference between the current in the main winding and auxiliary winding.
