 * This first para is just plain bull and wrong!!. Needs editing ASAP

An electrostatic discharge (ESD) is a sudden flow of electric current '''through a material that is normally an insulator. ''' A large potential difference across the insulator generates a strong electric field, converting the material's atoms into ions that conduct a current.Light current 00:59, 5 August 2005 (UTC)


 * First, current doesn't flow through insulators. Charge may build up and be stored on an insulative surface or material, but discharge occurs when a conductor approaches the charged insulative surface and a breakdown of the air (from a very high electric field creating a plasma or corona discharge) between the conductor and charged insulator (or isolated conductive surface) occurs, causing a current to and through the conductor (air to conductive surface).


 * Second, an isolated conductor can also store charge and when approaching or contacting another conductor cause an electrical discharge (see Van deGraaf generators).


 * Third, the first paragraph of this article does need to be re-written, as it is incorrect and misleading.Wolf 07:08, 10 December 2006 (UTC)


 * Attempt at re-writing first paragraph: Electrostatic discharge (ESD) is the sudden and momentary electric current that results when an excess of electric charge, either stored on an electrically insulated object or on an isolated conductive object, finds a path to an object at a different electrical potential (such as ground).   It is the large electric field between the two bodies that causes the ESD Event electric current to flow through the conductive path between the two bodies (including the electrical breakdown of the air) and the conductive body.  The term is usually used in the electronics and other industries to describe momentary unwanted currents that may cause damage to electronic equipment, cause ignition to explosive gases and is considered in the design of semiconductors.Wolf 07:50, 10 December 2006 (UTC)

?? How is that wrong? - Omegatron 02:27, August 5, 2005 (UTC) some people think if you have a generator with a a semiconducting track circling it with say 10 kw running the track spinning the generator producing say 100 kw as the arm from the track to the generator determins (ATR) Amount of torque required and you were say to put this in a Insulated vacum and run it off the power It produces and as Ions compress with increase of engine speed and electrical thrust and the (IPSI) Ionic pressure per Inch increases is released to a (HBT) hydrogen blast tube and Jettisoned It would have a similar resembelence to Lightning any comments? PapyZ1@Juno.com COMMENT: Do authors get to put a link to their websites on these articles? See External Links. (I would like to do the same thing, but wonder if that would commercialize wikipedia.) - A reader.


 * In general, no. However, if your website purely contains facts relevant to the article and is not about yourself, it might be tolerated. --Heron 23:09, 18 December 2005 (UTC)

Does anyone see a link of the last sentence in "Causes of ESD" to the ESD chapter (LSD)? TheUnremorsefulZork

Transmission-Line Pulse ESD Testing
In the last few years many papers have been published on TLP. I just referenced the first one which came up in a Google search. DFH 19:25, 2 July 2006 (UTC)

Diagnosis of ESD caused damage
We could do with a new section about diagnosis of ESD caused damage, e.g. in integrated circuits. Sometimes it can be wrongly diagnosed as "mechanical damage". See the paper by Jacob & Nicoletti in the external links section. DFH 11:05, 3 November 2006 (UTC)

Merger proposal
These articles are basically the same and the distinction isn't important. Gigs (talk) 19:41, 29 December 2008 (UTC)


 * Keep separate. These are indeed distinct topics. ESD is important in the study of natural phenomena and in the manufacture of discharge devices such as the Van der Graaf generator. The study and hardening of static-sensitive devices is a very different topic and is a part of electromagnetic engineering. -- Cheers, Steelpillow (Talk) 19:32, 27 January 2009 (UTC)


 * I have removed the merge tag from both pages. -- Cheers, Steelpillow (Talk) 20:09, 30 January 2009 (UTC)

Reference to electrical breakdown?
I think this article should mention in the intro that electrostatic discharge is a particular case of electrical breakdown that also includes "continuous" discharges such as corona discharge, glow discharge, arc discharge, and there needs to be a reference to the "Electrical breakdown" article (there is a ref to "dielectric breakdown", but it's hidden in the Sparks section). Also, I don't understand why the Sparks section refers to the article on corona discharge as the "main article". —Preceding unsigned comment added by 74.13.185.122 (talk) 01:14, 8 November 2009 (UTC)

Radiated fields caused by ESD
I'd like to see a mention of a causal phenomenon of ESD -- currents that cause radiated fields that can couple to conductors and devices in nearby electronic circuits and equipment.

Cause of ESD/Static Charge
One thing that bothers me is that this page says that static electricity is casued by friction. It is only caused by contact, friciton itself does not cause the electrical buildup of charges. The static electricty page has it right in any case, and it is only a minor change but should be done — Preceding unsigned comment added by 134.114.64.181 (talk) 18:09, 24 June 2011 (UTC)

Merging in Electric Spark into....
Talk:Electric_spark

I bring this up, as currently the Lightning page links to the Electric Spark page, and I feel that is a great disservice given the general overall quality of this page. As mentioned in link above, I think this page should be title "Spark" or "Spark/ESD". I would also point out, that the intro is too specific to the application of electronics, not the general phenomena we are looking at, but ESD is significant in electronics & should receive significant weight within this article. Another "electric discharge" page used interchangeably for consideration.... Electrical_discharge.

Comments, suggestions... Borealdreams (talk) 22:38, 13 March 2012 (UTC)


 * Oppose merging since electric sparks are only one type of electrostatic discharge. --Kkmurray (talk) 01:15, 15 March 2012 (UTC)

My apologies, I may have not been clear on what I was suggesting... Electric Spark into the ESD page. The same with the electric discharge page into ESD. Thereby the ESD page is the primary, with the examples/types under it. Which I believe is basically what you are saying as well. Borealdreams (talk) 16:45, 15 March 2012 (UTC)

A Spark Just Happens?
Where's mention of the basic physics on why it happens? Hmmm, nothing has happened to this page in nearly a year??? Given my understanding has improved in this time, I have made changes "Be Bold" that were needed, before I realized this.... As I read over this, I find it very odd there is no mention of Electric potential whatsoever. If there was no potential (a difference in charge) between two objects which have an insulator (generally a non-conducting medium) between them (air usually), there would be no reason for the charges to exceed the threshold of the insulator and form the resulting spark, which is equalizing (equipotential, making equal) the charge of the two objects. That is the absolute basics of bonding of metallic objects that may be exposed to combustible atmospheres, how is electric potential not even discussed here??? I'm going to ask this page is flagged, needing much improvement. Borealdreams (talk) 05:01, 21 January 2013 (UTC)


 * The term you edited out, "potential difference," means the same as "electric potential." But more important is the field strength - volts per metre - because that is what triggers breakdown of an insulator. Many of the pages on electromagnetic topics are in a similarly bad state, but until an enthusiastic author with a decent reference library arrives....
 * BTW, I think you were wrong to delete "explosive" from the description of lightning. An explosion occurs when a shock front travels through a medium faster than sound. When the lead of a lightning stroke travels faster than sound it creates just such a shock front - a clap of thunder. Prolonged lighting creates more of a peal of thunder. &mdash; Cheers, Steelpillow (Talk) 21:18, 21 January 2013 (UTC)
 * Hello Steelpillow. Thanks for taking an interest & comments. :)  I would agree, common speak would say the two are the equivalent, but potential means difference... so it's saying "difference difference" due to ambiguity of the word "potential" and is often confused.  For obvious clarity, I like "electric potential", as "electric" clarifies that it is electrical potential one is talking about.
 * With regards to "explosive", I can see your point, but when you mention "lead of a lightning stroke" we again get into ambiguity & common speak issues. Are you meaning during [downward] leader (just talking C-G for the moment for reference) formation as the ionic channel is being established, OR when discharge begins and the massive amounts of energy gets transmitted? I would agree during the latter, the shockwave could be "explosive", but I'm not aware that first part would be so.
 * Hehe, well THAT person is me & I've arrived! AND yes it is ambitious, trust me I know!  I'm trying to clean up everything with regards to lightning, in particular C-G & things that affects mankind's things, and although I've started & made some progress, I realized it was best to make sure all the associated pages are "clean" first.  Bringing the technical info is what I can really offer, formatting wikistyle I'm relatively novice at.
 * Any comments on my "discovered" realization... that in all of this there is no mention of charge[s]? Am I completely missing something?  Cheers & thanks!  Borealdreams (talk) 00:27, 22 January 2013 (UTC)
 * Hi there. My point was that there was effectively mention of electric potential until you edited it out. While one can argue about the semantic merits of "potential difference", there is no doubt that it is a widely used term. I would actually suggest that an electric potential was an absolute value at some point relative to some zero reference point. A potential difference between two points is the difference between the electric potentials at those points: that is, neither point is necessarily at zero potential. Many lightning flashes occur between two points in the sky, and so potential difference is the more accurate term for general use. But really, like I said, it's the field strength that is the critical thing and needs more mention.
 * You are surely right about the leader vs the main discharge: leaders often propagate relatively slowly, and the discharge doesn't happen until the leader has grown near enough to its destination to cause breakdown. Then, the supersonic propagation of the main discharge causes a massive thermal expansion of material and accompanying shock front which are the characteristics of an explosion.
 * Looking forward to your work. I'll try to find the time to clean up some wiki stuff, but I am no expert myself. Go to it! &mdash; Cheers, Steelpillow (Talk) 20:34, 22 January 2013 (UTC)

204.229.220.1 (talk) 00:32, 6 April 2016 (UTC)== Electricity Light Current ==

I understand about electricity static discharge and all over the charge. But this I may not proved nor accepted as a laws. I call it electricity interlightism theory. I was looking forward to the Li(light current) formulas. Its the measure of Power(Watts) per Resistance(Ohm). The energy is design as the heat and the ohm are independence. Sadly, it more likely algebra physics. As I wrote: 4*(pi)*β(velocity per speed of light (c))*ƒ(frequency)*θ(angle)*ΔE(energy)÷Z(independence resistance). I don't know how the over science would explain this as the new theory.

Yes, it me again. The Electricity Interlightism Theory is the realistic ionic current. I may know so far that I may say this: the particle movement is flown through between the energy of matters. If my words is true, then I know this is the new moderns theory. The Coloumbus's law that I reduced into the current is similar to my formulas. However, I was work so hard enough.

Thus, the energy that given is the photo-effective might had the clue for the state. It not clear enough for having heat energy that build up by the plates. I will say that this is also the state of matter. It can be solid, liquid, and gases. The most important is the dry states and wet states. But dry states is more dangerous than wet states. The independence resistance had similar as the generator(AC/DC) that prove the particles motion is jagging. And charge is there but depend on the amount of field. In real world, the particle of amp doesn't simple and details. But the particle charge itself, the one that move across.

Electricity Light Current
I'm terribly sorry, I accidence put on somebody else thought. The name Gerald, I works hard enough to find out what all about. I been looking for information and spend time at home, library, and computer. It is the new theory that I might add to it. I might relizes that it call Interlight Discharge. I also woundering about the particles charge diagraim too. The ions twisted and squeaze to release the heat and sound energies. — Preceding unsigned comment added by 24.121.176.106 (talk) 00:14, 27 May 2016 (UTC) Hello, it me again. I just reduce the formulas into kinetic energy and potential energy, and I just solve another answer. But this only required into plasma physics, nuclear physic, and quantum physics. My diagrams are similar to Birkland's Current that show his details, I also seen the Primer Fields (which it had been discover ago). The kinetic energy is the measure of momentum while it kept flowing. And potential is the part of matter of field (which increase the thermo frequency.) I really disagree about the lightning's created, the hail and the rain doesn't form like that. What I need is to find the result about the different between the Kw formulas and the changes in fields. Also there the level among the matter that cause the affection to move into different levels. If the particles are really close to the potential matter, will changes the labels into different section. I also conserved about mass, dielectric, and frequency that needs to solve this. Meanwhile, the potential matter will relocated in different distance. I agree that the levels are reference to radius length, it like some like chemical bond levels. — Preceding unsigned comment added by 76.113.40.216 (talk) 22:41, 29 September 2016 (UTC)
