Drawing Electric Arcs at 230 Volts

AI Thread Summary
Electric arcs can be drawn at low voltages by separating electrodes, but achieving this at 230 volts can be complex. The user attempted to create an arc using a kettle as a power resistor with two iron nails as electrodes, but only produced sparks. They experimented with a diode bridge to convert AC to DC, yet still failed to generate a proper arc, suspecting the need for a filtered DC current. Responses in the discussion emphasized the dangers of such experiments and recommended seeking safer alternatives. The thread was ultimately closed due to the hazardous nature of the topic.

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 :)

My goodness that looks dangerous.

It's easier to draw a good arc at ~220 volts with DC.
 
Thanks for your reply nsaspook 🙂 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 ?

Sorry, NO! I can't help you with this potentially dangerous experiment.
 
Thread closed. PF does not allow dangerous topics.

@Quentief , Please stop these dangerous experiements before you or someone else gets hurt. You can find plenty of videos on Youtube that show similar experiments carried out in safer laboratory conditions. Those videos can satisfy your curiosity.

@nsaspook and all other members, please note that you do us a disservice when you respond to topics like this rather than report them.

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
