tesla effect
The June 7th revision by 204.56.7.1 again refers to a "Tesla Effect". On the same date, the same author also provided a new Wiki page that defines the Tesla_effect. However, the newly listed "effect" does not appear to fit the definition of an accepted scientific phenomenon, nor does it appear to be defined as precisely as all of the other effects currently listed in Scientific_phenomena_named_after_people. And, the new Wiki page that explains the "Tesla Effect" is not much help since it initially seems to imply a high voltage/capacitive effect, but then refers to electromagnetic induction. A Google search indicates a number of conflicting definitions for the term "Tesla Effect". And, virtually all of these references come from non-scientific/pseudoscientific sources. Although I can appreciate the author's attempt to honor Tesla in this fashion, I still recommend deleting reference to the "Tesla Effect" since it's ill-defined and is not an accepted scientific phenomenon in the league of other named scientific phenomena. Thoughts? Bert

These sources cite the "high voltage/capacitive effect",
- Norrie, H. S., "Induction Coils: How to make, use, and repair them". Norman H. Schneider, 1907, New York. 4th edition.
- Electrical experimenter, Janaury 1919. pg. 615
I will be adding other citation (as there are others) when I can. Norrie make reference to it's use in electrothreapy and lighting. There is a really good article about Tesla's wireless lighting that has the digram of the effect, written in Tesla's time .... it talk about his lighting effect (2 plates and a HVHF generator or another AC source; take his wireless bulb between the plates and it lights up) .
- As to it not being like the other effects currently listed in Scientific_phenomena_named_after_people, it is list just like Edison's effect is listed.
Wardenclyffe Tower
The qualified statement "This type of coil may have been used as the basis for the Wardenclyffe Tower project" seems timid; if you have a look at the tower it is obvious. Waveguy
violet wand
The violet wand edit appears to advertise an unrelated subject.
There is no link between violet wand (Erotic electrostimulation) and tesla coil (electronics), save for the fact that one uses the other. Many thousands of objects use wood in their construction, but wood does not direct a reader to each. I believe it would be unlikley that someone looking into this aspect of electronics would appreciate being directed into an unrelared field.
On the contrary, the violet wand was a Nikola Tesla invention: a handheld Tesla coil connected to a gas discharge tube intended to be applied to the skin. His invention was an electrotherapy device which today is regarded as quack medicine. Numerous companies began copying Tesla's design, prompting Tesla's financial adviser to complain that Tesla was losing millions of dollars by not defending his invention. Tesla refused to pursue the copycats.--Wjbeaty 10:35, Jan 1, 2005 (UTC)
Adjustments :
- quote "It is advisable to begin the adjustments with low-power and low-frequency oscillations" This sentence does not make sense. I agree with the low-power part. But the purpose of the adjustments (tuning) is to adjust the resonant frequency of the primary circuit to match the one of the secondary. Therefore, you don't run your coil at a lower frequency to make adjustments, but you run it at low-power to make frequency adjustments. Would you agree? (I open the discussion, and I'll change the sentence if I don't get a negative feedback...) Glaurung 12:58, 3 Nov 2004 (UTC)

For anyone, curious this article is horribly out of date. I think I am going to start a re write. Eric Urban 04:30, 19 Dec 2004 (UTC)
skin effect
Skin Effect Edit: I did some significant rewording to correct a potentially dangerous misconception that Tesla Coil sparks are not painful because "skin effect" causes most of the current flow on the outside of the expeimenter's skin. This is a very popular misconception, but it can easily be proved as being false. The misconceptin could lead to injury or even death of careless or unwary experimenters. --Bert 17:07, 6 Feb 2005 (UTC)
I also agree with Eric Urban that much of the text is out of date. Have added some verbiage about the nature of Tesla Coil discharges and did further edits to the Skin Effect area, making it a separate section. --Bert 15:00, 7 Feb 2005 (UTC)
This article (and derivatives) is the only place where I've encountered a Tesla Coil being called "self-regenerative resonant transformer". Today, this device is more accurately known as a "dual resonant air core transformer" to reflect the fact that there are two coupled LC circuits. The source for the "self-regenerative" term is probably from one of Tesla's patents, but the term is really no longer used to decribe resonant transformers today. Perhaps we could acknowledge Tesla's terminology, but I'd recommend also indicating that the modern-day term for this device is a "dual-resonant, air-core transformer". Using the more accurate/modern terminology would also help researchers find other modern-day applications. Thoughts?--Bert 15:00, 7 Feb 2005 (UTC)
- I agree. This article needs major re-work and organization. I was expecting much from Eric Urban's rewrite, but he apparently disappeared from Wikipedia before changing anything important. With some work, and additional pictures, this could even become a featured article. Glaurung 07:16, 8 Feb 2005 (UTC)
Alternating current driven for transceiving
I removed this and placed a different explanation in its place. Tesla coils do not transceive. True, the secondary coil and its capacitor can be used in receive mode generally Tesla coils are not driven for such purpose given the poor radiation achieved.
Rewrite
I am beginning a rewrite as of 12/23/2004. Eric Urban 04:43, 24 Dec 2004 (UTC)
- I think you should write something about it on the article. Something like {{inuse}}, but not sure if that's for full rewrites that take time — Kieff | Talk 14:03, Dec 24, 2004 (UTC)
I suggest that all references to Nikola Tesla in the Tesla coil article refer to him by his full name to avoid confusion with the discussion of the Tesla coil itself. I am doing so in my rewrite.Eric Urban 03:17, 26 Dec 2004 (UTC)
- The template {{inuse}} should be used for a limited amount of time. You can put it while you are editing the page to avoid editing conflicts. But you put that warning two days ago and you haven't edited the page since. So I would suggest you remove it and put it back when you will really be ready to edit the page.

Command and Conquer
Tesla coils feature in the Command and Conquer series of strategy computer games, as a weapon on the Soviet side. What sort of heading could be added to this article in order to mention this? Something like "In entertainment"? –– Constafrequent (talk page) 03:14, 31 Jan 2005 (UTC)
- sure. - Omegatron 04:04, Jan 31, 2005 (UTC)
- try putting it under the "Tesla coils in popular culture" heading... when someone makes it Cal 1234 15:10, Feb 7, 2005 (UTC)
waveform
i'd love to see a waveform of the output of a coil. I imagine it's a high frequency wave periodically decaying exponentially? triggered each time it sparks? - Omegatron 16:37, Feb 7, 2005 (UTC)
It's actually considerably more complex than that since the energy in the secondary builds over a number of cycles, and the output waveform is dependent on when the primary spark gap stops conducting ("quenches") and whether or not there are discharges that are also removing energy from the secondary. See the following sections of Richie Burnette's site for some of the gory details:
- Tesla Coil Operation, Notches, etc (http://www.richieburnett.co.uk/operation.html#operation)
- Quenching, etc. (http://www.richieburnett.co.uk/operatn2.html#quenching)
Happy reading, --Bert 18:10, 7 Feb 2005 (UTC)
