[Amps] S W R

[Bob Maser]

Actually, the scenario you describe would show more than 100 out because the 
10W being returned would increase the apparent output so your ridiculous 
argument doesn't make any sense, unless, of course, if you lived south of 
the equator, in which case all of the reflected watts would spin CCW and 
your toilet wouldn't flush.
