Hi everyone :)
I open this discussion because I would like to know how electric arcs are able to be drawn.
Indeed, I have been told that it is perfectly possible to draw electric arcs at very low voltage, by simply putting in contact two electrodes and then drawing them apart. I wanted to try it by my own but it doesn't work and I would like to know why.
Actually, I have made a simple circuit which is consisting of an electric kettle plugged in the main 230 volt. Two electrodes are connected in series of this kettle. Indeed, I use the kettle as power resistance to limit the current. The electrodes are simply two iron nails.
I know this circuit is very dangerous, I do not approve it and I would not recommend to anyone to build it. But well,... it's a very simple circuit and very cheaper to make, so despite the risks I think it's pretty good way to make some tests. Anyway, I am very awareness of the risks and I am very careful.
So, the reason of this topic is simple : it doesn't work, I get only some sparks but nothing which looks like to an electric arc. Futhermore, I saw several videos where people claimed that this is perfectly possible to draw electric arcs at the main voltage (230 volts) :

Some of them say that I need to use a DC current, so I bought and wired a diodes bridge to rectify the signal, but I have the same result as before.
I don't understand how they do, but apparently it's possible. So the question is, what's wrong with my circuit ? If somebody have the answer, I'm more than interested! :)
Thanks in advance for your help :)
Postscript: sorry if my english is not perfect, actually I'm french
but I will try to do my best!

yes this is exactly what I am looking for but like I said it didn't work with my circuit, even if I use the diodes bridge. I suppose that's because I don't have a perfect DC current, it needs to be filtered. Please, could you tell me how can I design a coil or a capacitor in that purpose ?
