Hi Nicholas,

A correction on my part: I put 900 ohms in place of 10A:

Let me rewrite this:
The problem is, your not discharging 10A in a thousandth of a second. If 
you want to limit the current to 10A, then time must be dramatically 
increased. Say 9000V/10A = 900 ohms. Then t = (CV)/I = (.003F * 9000V) / 
"10" ohms = 2.7s, and 2.7s * 5 = 13.5s for full discharge.

Sorry about that. Popped in R in place I. Of course, another way to look 
at this is that if you had a transformer that could put out 9kV at 10A, 
then it would be slow 13.5 seconds before the cap is fully charged. 
0.003F is simply an extremely large cap size to charge to 9000V.

Take care,
Bart
