content: Hey yall, Igor here, it's sub zero temperatures in NYC, winter, and static is just horrible, especially for my Siberian furry cat, any time i touch him we both get shocked, humidifying air doesn't help much, so I was pondering as you do and came up with this simple schematic, any ideas on whether it will work and what specs would I need on the capacitor, diode, rectifier and xenon flash?the accumulated charge off your body converts into DC by the rectifier and charging the capacitor, the capacitor once charged will then self discharge through the Xenon flash, xenon flash is arbitrary, any high current lamp for continuous discharge would work just as well I think

content: Quote from: Undweeber on February 14, 2015, 07:08:33 amAsk yourself, why do you get a static shock.Answer: because there are two radically different (static charge) voltage potentials, one thing high potential, the other thing low potential.Ask yourself, why do I not get shocked a second time if I touch and then touch again the same item.Answer: because you have equalized the potentials, you and the object you touched are at the same potential.Ask yourself, how does my device make me and the object I am going to touch be at the same potential.

content: Quote from: Undweeber on February 14, 2015, 07:20:34 amYou can't just "get rid of it", you have to equalize between you, and the thing you want to touch, a transfer of charge.Look at (real, not those fake wireless ones) ESD wrist straps, inside is a 1M resistor which is connected to a wire, which has a clip on it, you clip the wire to your work surface, and any static imbalance travels through the resistor, nice and slowly so you and your components do not feel it, to equalize you with your work surface (which may be equalized with ground as a convenient reference).Your static charge is not AC, it (you) is all the same potential, you don't have 30kV on your nose and 0V on your toe, you just have 30kV of potential difference with REFERENCE to something else (your cat), if you grabbed both ends of that AC input you've drawn, you accomplish nothing, both ends are at exactly the same potential, it would be as if you connected both ends to the positive of a battery and left the negative wafting about in the breeze.If you want you can imagine you and your cat forming a charged capacitor, together, but on your own, you are just one leg of that capacitor, and you can't do much with a one legged capacitor, if both legs of the capacitor touch, you and the cat, zap, current flows instantly and the capacitor is discharged, if both legs touch through a resistor, current flows slowly and the capacitor discharges in a slow controlled manner.I guess maybe if you held one end of the AC input and asked your cat to hold the other end of the AC input, you might get somewhere maybe, but my cats are not so co-operative.

That should set you both at non-zapping levels.

I dont like the idea of equalizing the electric potential, this is not what I am after, I want to discharge the charge I accumulate, I will not make it magically disappear, I will convert it into flashes of lightQuote from: rodcastler on February 14, 2015, 07:59:10 amtoo primitive

content: Quote from: Undweeber on February 14, 2015, 07:20:34 amI don't think you quite understand what potentialis. It's not something that can be got rid of. Consider that everything in the world has a certain amount of charge in it. Ithas tobecause the electromagnetic effects of this charge are a huge part of what actually holds matter together! Chemistry couldn't work without charge.Electric potential is what happens when one thing has more charge than another. It's not what happens when somethinghascharge - as I pointed out, all things absolutely must have some charge - it's what happens when something hasmorecharge. Removing potential and equalizing potential are the same thing. You allow the excess charge to flow to the place that is relatively lacking charge, and now they're equal, so there's no potential.For an analogy, compare electric potential to the potential energy of gravity: EP(grav)= magh; given ag= 9.8 m/s², if I lift a 1 kg object by a height of 1 m, it will gain (1 kg)(9.8 m/s²)(1 m) = 9.8 J of energy. But you can't get rid of that energy! Even if I place the object on the ground, I can give it potential energy again simply by digging a 1 m hole and placing adifferentobject in the hole. Then it again has a relative potential to this different object. There is no way to give something "zero" EP(grav).All of these various ideas to get rid of potential do the same thing: by applying it to some device that converts potential into current, you draw the charge out as current and dissipate the energy as heat into the device. No matter what the device is, it's doing the same thing. Might as well use a resistor. All you're doing is making this over-complicated, and also making it not work as well. Anything like a neon lamp will stop conducting once the potential drops below a threshold, so it's not capable of getting rid ofallof the potential which I imagine is something you'd like it to do.Side note: this absolutely requires you to touch ground - if you don't apply a potentialacrosssomething no current will flow through it; it can't "see" any other potentials. "Your potential" is a potential to ground so you must apply device between yourself and ground.Other-side note: your potentialisDC, there's no point in rectifying it. Almost all naturally occurring potentials are DC, AC tends to be man-made.

It would work when used in this manner but resistors are far cheaper and more reliable.

content: Did the OP say where he is going to connect the two input leads of his device. If the OP can specify an input wiring scheme, he may understand the misconception in the design easier. Or, the OP may want to think why his design should be better than a minimum design that just short the two input leads.QuoteApparently, the OP confused two different concepts here. In simple terms, "electric gradient " (E field) is, as the name implied, the math gradient (or spatial derivative) of the "electric potential". "electric potential" is uniquely definable up to an arbitrary constant. This arbitrary-ness means only potential difference has physical meaning.Though, conventionally and conveniently, zero "electric potential" is attributed to the electric potential at infinite far away from any electric charge. Then, in practical use, "infinite far away" has never been farther than the thing under one's foot, which we call earth or ground.Is basic physics a part of college biology program?

It doesn't matter, I promise you that if Ohm's law stops working you'll have more to worry about than ESD... you can trust that the resistor will work. Ohm's law has been around since the nineteenth century.QuoteThat's not how a resistor works. It "resists" current simply by limiting the amount of current that will flow for a given voltage. Any resistor will still conduct if any potential is applied to it, an amount determined by Ohm's law, so a resistor will drain offall the charge*. The same can't be said for:QuoteCapacitors won't take all of it! You are a capacitor too. When you connect the two, they'll justsharecharge. It'll take some portion of the charge, but not all. As soon as the two are equipotential, current will stop flowing.QuoteAn incandescent bulb is just a resistor. All you're doing is using a capacitor to transfer charge to a resistor - why not transfer it more directly?QuoteThat'll work too. Like I said, however, there often won't be enough charge to make a noticeable light, so it's pointless.QuoteLearned about mitochondria and ATP in high school, dude, no need to study bio. I just don't see how it's relevant.*Pedantic footnote: it'll drain off the chargeasymtotically, so you'd have to wait an awfully long time for every last single electron to be gone. Still, it'll be over 99% gone in under a second for any reasonable resistance.

content: The problem is that you can't prevent the charge since you are isolated, also since your circuit is isolated as well with you, there is no potential difference unless you reference it to say ground so the circuit will do nothing unless you have a wire grounding you at which point you are not holding a charge anymore so you don't need the circuit.All of this won't prevent a potential difference between you and the cat unless you both have a common ground contact so that you and the cat are at the same potential charge.

content: Because you also have capacitance. The charge will flow to the capacitor, but it will equalize with some charge in you and some in the capacitor - more charge in the thing with more capacitance."Now hold on", you say, "this is a 40001943uF capacitor!" But that's the capacitance between its two plates. To make charge flow into that capacitance (that is, between the two plates of the capacitor), you must apply a potential differencebetweenthe two. That is, negative on one side, positive on the other. Your entire body will be at a nearly equal potential, as it's conductive and so self-equalizes, so you can't do this. You don't have any differential voltage to apply to the capacitor.All you can do is apply charge to the capacitancebetween the capacitor and ground. This is a function of its size and its physical distance to ground, and since it's much smaller than you, so is its capacitance.Most of the charge stays on you.Also, what IanB said. Just stop wearing slippers. I go barefoot in the house and pretty much never pick up any static (before you ask, yes, it's a dry winter here in New York). Any charge I pick up is conducted right back out my feet. This habit helps keep me from shocking not just angry cats or dogs, but also expensive electronics.

content: It doesn't work because somewhere along the line you misunderstand what static electricity is and how potential works.Remarkably in trying to think of a way of explaining it in simple terms I am struggling to think of a way that is clear and simple. However here are a few things that might help.Firstly AC is a red herring, the shock you get from static is DC.EVERYTHING has a potential and is relative to everything else.Static electricity is caused by an imbalance of electrons on a surface. Atoms normally contain an equal number of protons (positively charged particles) and electrons (negatively charged packets of energy). When they don't, for example by electrons bing stripped from a surface due to rubbing, when the two materials make contact, electrons jump from one to the other to fix the imbalance giving you a shock.Humidity plays a part as moisture makes the air more conductive, so it acts as a giant resistor connecting everything together so excess charges are (slowly) distributed making everything a similar potential. On dry days, objects hold static charges so any low resistance path between them such as objects touching (you and the cat) causes a sudden equalisation causing the shock.Somewhat confusingly hot air holds more humidity than cold air. So even though everything look dry on a hot day there is more moisture in the air.

A resistor is connected between the two objects with a static charge or that have the potential to become charged and dissipate the energy in a controlled manner.

content: lol thanks for support and advise guys, i just walk around twice a day with a sprayer and spray my apartment with water, less shock that way, plus its getting warmer now, cat resistance was the cause of my experimentand yeah i realized on practice what potential was the second i hooked up everything, I ended up with two wires, not one, seems like without ground it wouldnt work..
