Of course, "I" am the first one to mess up. :-|,
I dropped a zero somewhere when I calculated the capacitance...
It is 8.63nF .
I used a Y2K certified HP calculator too, so I can't blame it on that....
I just saw the Jim Lux used a K of 4 and interpreted "0,5 m^2" as being
0.25 meters squared instead of my taking it as 0.5 meters squared so his
answer was 2.2nF...
I knew this would happen... These tough questions always kill us... ;-))
