Thank you so much for all the information. As usual, things turn out to be more complicated and need more attention than meets the eye of a little-experienced amateur. I will try to digest the advice, and do further research (and experimentation). Hopefully, I will end up with a workable...

OK, I think I am well on my way now. Thanks a lot for your help!

Thanks a lot, Sir, that cleared up my main issues. The quality of the output voltage is not a big issue, I believe, because I am going to pass the output DC to several smaller "client" power supplies, which are based on regulators. For these, I aim at somthing around 12-15V maximum output...

Folks I am about to build a 2 * 8A DC power supply from a transformer supplying 2 * 8A 18V AC (transformed from 230V 50Hz house current). I have been dabbling a bit in electronics, but I am no expert. A formula that I found on the web, ( C = 0.7 * I / (dE * f) where C is the capacitance...

The answers posted seem to be in nice accordance with the physics I was taught in high school. However, in practice they fail dismally, unless one at least brings the area of contact between the two surfaces into the equation. There is a reason formula one cars have tyres as wide as a barn door...
