To me the terms involved are open to too many interpretations. As evidenced
in this thread, I suppose.
Where *do* you get this requirement for changing polarity? We
don't call it "Alternating Polarity", we call it "Alternating
Current". If the current is being altered, it's AC.

No, if the direction of charge flow alternates between two states,
then it's Alternating Current.
That fits my definition, but not yours! Are you changing your definition
or is that just a momentary bit of logical thought?
The states do *not* have to be plus and minus polarity. Just different
current levels...

You keep talking about AP, and it isn't the same.

Yes, it is. In order for the current in a load to alternate, the
polarity of the generator's output voltage must alternate as well.
Sure. But it doesn't need to change polarity. All it needs to do
is change level.
