Only in extreme cases, and I'm not sure you would notice.

Draws current on both halves, that's what bridges are for!

No, it't just that it only draws current during one half-cycle.

Yes, half wave draws current during half the wave.
Full wave draws current during the full wave..

Pretty well, usually.

I would have a link to http://www.findu.com/cgi-bin/find.cgi?KC6ETE-9 here
in my signature line, but due to the inability of sysadmins at TELOCITY to
differentiate a signature line from the text of an email, I am forbidden to
have it.
