And again I say, nay, yon device is not necessarily a capacitor, simply
because thou canst reduce an AC component with it!  Question: what do you
get if you connect a source supplying a combined AC and DC voltage (the
rectified output of an alternator, say), across a *DC voltage source* with a
fairly low series resistance (say, oh, jest fer grins...A BATTERY!)?  (For
further amusement, consider applying said signal across a "pure" DC voltage
source - i.e., no series source resistance.  Of course, this is meaningless
unless you assume that the AC/DC source includes some source resistance of
its own, but I think you're getting the idea by now.)

Question the second: If the battery in question is really acting as a big
capacitor, comment on the expected phase of the AC current through it,
relative to that of the AC voltage applied across it.  Hmmmmm?
