YT2095 Posted March 6, 2006 Share Posted March 6, 2006 I`ve just finished a small Voltage multiplier 10x 0.1mfd capacitors rated at 1kv each in a 5 stage ladder, I`ve powered this up at roughly 1kv at 8Khz (current unknown but quite low). I get a half inch spark every second (a little less time on occasion) and the sound is like a Whip cracking with a bright UV type flash (I still have spots in front of my eyes). I thought I`de intecept this arc with an old envelope laying about on my desk, it still worked, but there`s a series of tiny holes through the paper now, including the part where the sticky is, about the size of a pin prick. the REALLY interesting part is that upon closer examination the "Blow out" hole it towards the Possitive side of the electrode. a bit like firing a ballistic round at a tin plate, one side has a smooth dip with a dent Inwards (concave) the Other has the hole with lots of sharp pointy outy bits and a the convex dent. the concave was the Negative side, the convex was the Positive side. and other than a VERY slight yellowing around such tiny pin holes, there is NO burn marks at all. Truly Fascinating! I can only assume for the time being that it`s all to do with electron flow from Neg to Pos and that`s also what carries the Momentum for the mini "Blast" holes.

swansont Posted March 6, 2006 Share Posted March 6, 2006 Sounds a little like a spark timer from a freshman physics lab of a few years back. Drop a mass with a paper "tail" through it, and the sparks mark roughly constant time intervals, so you can measure g. I don't know if it was that paper's composition, but I recall some charring in that case. Link to comment Share on other sites More sharing options...
YT2095 Posted March 9, 2006 Author Share Posted March 9, 2006 Hmmm.. it was probably at a high frequency if it caused charing, I have a transformer here that I run at about 10Khz only delivers about 3kv the arc will set fire to paper instantly, it`s a purple(ish) arc and gets quite hot, whereas the multiplier I used above is DC and makes a very loud Bang sound with a bright white/blue Lightening color flash.
