Hey Deph. :thumbsup:
I think the scheme here wasn't to hook up the lamp
in series with the cap (although of course, that's what King and I were referring to) but I think what Spac was talking about was just sitting the cap in front of the lamp - no electrical connection as such. What you say is absolutely correct - if you DO hook up a globe in series with the cap, once the lamp goes out the cap is charged, given that a charged cap is open circuit to DC. (well, for all practical purposes anyway)
I can see what Garfa is on about - I think - but jeez, I still reckon it's a rather wasteful way to charge a cap in comparison to simply hooking it up with a resistance in series - such as a test light, resistor, or whatever. Great practical demonstration, but your battery will get a bit upset....
Still - it's a neat trick!
