Hi,

It is cool to figure out the current!!

I have a Maxwell 37667 here...

35nF at 0.02uH inductance.  I am sure they figure that by shorting the poor 
thing out and find the frequency...

F0 = 1/ (2 x pi x SQRT(L x C)) = 6MHz

Xc = 1 /(2 x pi x Fo x C) = 0.756 ohms

I = V / R = 35000 / 0.756 = 46296 amps!!!!

The energy is 1/2 C x V^2  = 21.4 Joules.  (a lot!)

So that is real bad for them.  Sort of like running over a traffic light 
with your car.  You can get a few of them lights..., but the car is going 
to die real fast...

Cheers,

         Terry
