Expert Answer

Step 1

Given: Inductance, L = 27 mH

Resistance, R = 15 ohm

Frequency, f = 60 Hz

Voltage, V = 120 V

Find: (a) The rms current that the motor draws.

(b) By what angle, does the current lag the input voltage.

(c) The capacitance of the capacitors that should be connected in series with the motor to cause the current to be in phase with input voltage

Step 2

First calculate the inductive resistance of the inductor as:
