How does a capacitor function in a 120V AC motor circuit?
Without a capacitor, the same thing would happen to the start windings. Problem there I guess is that both windings would be in phase and thus no spin created for the rotor. So, a capacitor is wired in series with the start windings which I kind of understand. But I don''t know how the voltage and current behave.
