a question about resistors in an arc experiment

I see you're also well versed in french. :)

Well, that just blew their 'AlwaysWrong' claim all to hell with a nuke.

Irreversibly stained, that claim is, I'd say.

Who knows? Maybe the Bulb is only bright for those that have full spectrum vision as opposed to fool spectrum vision.

You should see my forest fire fighting solutions. Mark my words... it ill be what gets used one day, whether I bring the idea 'to light' or not. I cannot believe it has not already been thought of.

Yes. I note that your thick headedness increases without limit.

I cannot believe that you cannot see the flaw with your remark.

And that, folks, is how we got our solar system. Good thing a lot of that Iron ended up in this hulking spheroid.

When the Cycles Of Time come back around again, you won't even know that you have already been here before. Oooops... too late for that.

Except that *that* is not all that was wrong with his remark.

Whatever.

I think you miss understood him.

It is very clear to me.

It is obvious that he did think such a thing.

The 'dead short' of the two nodes between which any arc might occur, is the highest current value any source feeding it can provide. Separate the dead short and apply an arc, and you will NEVER get to that dead short resistance in free air. The arc goes to very nearly zero ohms, but not quite.

Both cases, however, will have very nearly the same current figure, and both will also likely cause the supply to fold back. IF the supply is made to sustain a specific current into a dead short, yet arc at HV when there is a gap, that arc will never be any more than that limit value for current.

The dead short will read zero volts across the shorted nodes, and the live arc will read whatever the sustaining voltage is to hit the current limit for whatever given arc gap (up to a point). So that one will read several kilovolts, and it will be very spikey. Make sure you use protections for instruments, etc.

It NEVER "led to unlimited current".

This is the reason why more of the element "burns away" before the circuit actually opens.

Bwuahahahahahaha!

That arc had to originate from between two nodes of conductive media.

The current through a gap, filled by ANY medium (including plasma), will never be higher than those two nodes shorted together.

Excellent and succinct. No one can argue with those scientific methodologies.

I used to make getter supplies, and flash lamp stimulus supplies.

I have no idea what you are talking about.

Connect two fat wires to a hefty 120 volt outlet. Touch them together, very gently. Wear sunglasses. No matter how delicately you make the contact, you'll get an explosion; the higher the capacity of the supply circuit, the bigger the bang.

Try it.

Repeat with, say, a 10 ohm resistor in the circuit, like the iron. You then can touch the wires together, and then pull them apart, and maintain a stable arc, at least if the wire doesn't eventually heat up and melt. But there will be no current runaway, no explosion, no matter how many amps the outlet is good for. Positive net total resistance makes the current stable.

Try it.

That's electrical reality. The rest of the nonsense here is just a heap of words and people acting pissy about definitions.

Crikey! Another nym! TURD!

...Jim Thompson

Right. When an EE says "negative resistance" he generally means some negative slope on the I:E curve. Things like "negative resistance region" and "negative resistance oscillator" are common. Phil Hobbs recently noted here that one can linearize a platinum RTD by connecting it across a negative resistance, and nobody was confused by that.

Most of us know that there are few true negative resistors in the Mouser catalog.

You are the rest of the nonsense here.

Lamefuck! Another pussy post! Uncivil fucktard!

BULLSHIT
