Need a clue? Click 'help' then 'about'.
It will even tell you your version number, your's is 6.00.2800.1106
by the way. :O|
About time you upgrade that old email client to the latest version?
You won't regret it :O|

And your's is 6.00.2800.1158, what's your point?

I guess that depends on whether you are using a proper newsreader
program or just any old e-mail client to read newsgroups.

Big?

Current path would be...???

Backward through the rectifier.

Fine, but where from there? The entire path. There isn't one.

A 0.1 Farad at 300 V is more than a "decent sized" capacitor.
For example most PC PSUs contain two 470 mfd capacitors each
charged to about 160 V. The energy stored is 1/2 C E^2 = 1/2
470 x 10^-6 x 160 x160. This is about 6 J or 12 J for the two.
This would keep a 12 W bulb lit for one second.

A monster. That would take 1 amp flowing for 5 seconds to charge
to 1 volt. To discharge it in 10 microsecs would require 500,000
amps.

Yep, and there's a 10 on the way...
