I have read thoroughly first two chapters about AC and ask: what is the sense of introducing the polarity for an AC?
Is it made for completing the tasks like in http://www.allaboutcircuits.com/vol_2/chpt_2/8.html, when reversing one source?

Hello: I'm trying to work my way thru allaboutcircuits. I'm stumped on "More on AC Polarity". How did they get 14.861 V and 16.59 degrees out of the two indicated voltages of 10 V and 0 degree and 6 V and 45 degrees. To me, I understood pretty much the preceeding pages before this, but I'm just not getting this at all. Thanks, Brad C.
If A.C (alternating current) changes its direction it means that both terminals should be phase. but there is always a neutral in A.C which is the returning path for current. I want to ask why there is a neutral in A.C? Does it also has a polarity when A.C changes it's polarity?
