If anyone cares about the whole AC capacitor for starting a single phase AC motor thing, I found the following link which appears to be perfectly accurate, well explained, and hopefully intuitively helpful for anyone who wants to understand the need for it, how the 90 degree phase shift is created, etc. (all that in one sentence, BTW, )

How does a capacitor function in a 120v ac motor circuit? - Electrical Engineering Stack Exchange
