Guest mancunian Posted December 19, 2003 Share Posted December 19, 2003 What is the voltage required for the effect to be produced ? I would like to know the lowest possible voltage that would need to be supplied. Thanks in advance. Link to comment Share on other sites More sharing options...
YT2095 Posted December 19, 2003 Share Posted December 19, 2003 that all depends on a good many factors. the vacume used, the distance between electrodes, the frequency of the voltage applied etc... there is no real limit from the molecular scale upwards. but here`s a small one you MAY have seen, ever seen the tiny mains neon bulbs? they usualy give an orange glow between 2 electrodes as the neon gas is ionised, well that is a plasma and they trigger at about 90 volts. hope that helps a little Link to comment Share on other sites More sharing options...
iglak Posted December 19, 2003 Share Posted December 19, 2003 but that's a little different from a plasma ball, isn't it? Link to comment Share on other sites More sharing options...
YT2095 Posted December 20, 2003 Share Posted December 20, 2003 well a plasma ball to my understanding is an evacuated vessel with a trace gas present through which an electrical charge is introduced at such a potential that the gas glows. as seen in many lighting shops and novelty gadget stores the vessel is usualy spherical giving it the Ball shape. a free plasma has no definable shape per se Link to comment Share on other sites More sharing options...
Crash Posted December 21, 2003 Share Posted December 21, 2003 Or they might be referring to the plasma balls mentioned in a new scientist magazine early this year, which exert almost all properties of a living organism Eg. movement reproduction, and can be made from a short sharp jolt of electrickery in the right conditions. They were discussing if life colud of started from these "plasma Balls" Link to comment Share on other sites More sharing options...
iglak Posted December 21, 2003 Share Posted December 21, 2003 i could swear i replied to this earlier today... oh well. i realised that i was thinking of ball lightnings here's a site about plasma balls/ball lightnings here's a site selling "plasma balls" and here's a news article about it. <edit> i just remembered, i did post here already today. i specifically remember editing it 3 times as i found those 3 sites off of a search engine. i wonder why my post was deleted.... and i posted on the "Return of the king" thread too, and my post isn't there now... hmm....
