Adding References to Articles[edit]

This help request has been answered. If you need more help, place a new {{help me}} request on this page followed by your questions, contact the responding user(s) directly on their user talk page, or consider visiting the Teahouse.

I have added references to a few articles that had no references. It has been a few months, but the articles ares still flagged as having no references. How do I get that changed? (talk) 11:09, 20 October 2010 (UTC)

If you are sure that a warning notice is redundant, you can remove it yourself by editing the article in the normal way. Right at the top you will find something like "{{Unreferenced|date=somedate}}" or perhaps "{{Multiple issues| ... Unreferenced=somedate ... }}". Be sure to fill in the edit summary clearly, something like "Removing the unreferenced tag because there are now 8 references", so that other editors know what you are doing. Do not mark the edit as "minor" -- John of Reading (talk) 12:13, 20 October 2010 (UTC)

Toroidal inductors and transformers[edit]

I added to Talk:Toroidal inductors and transformers. Your pix would be good in Rogowski coil. Thanks for your efforts. Glrx (talk) 03:08, 20 October 2010 (UTC)

Yes, I know your pix are public domain. I pointing you to an interesting topic and offering you the edits. Glrx (talk) 03:23, 20 October 2010 (UTC)
Thanks for the kind words, but I don't know anything about Rogowski coils.

I read some of your page, most of it is books and thought these internet links might be useful, this one has some pictures.[1]. This one has some more diagrams.[2] The rest are a bit complicated to explain.[3],[4],[5],[6],[7],[8]. This is a good one,[9],[10],[11],[12],[13],[14],[15]. I`m not sure if you got this one already.[16]. That`s all I can find at the minute. —Preceding unsigned comment added by (talk) 14:32, 13 December 2010 (UTC)

Requesting help on misspelled file names[edit]

This help request has been answered. If you need more help, place a new {{help me}} request on this page followed by your questions, contact the responding user(s) directly on their user talk page, or consider visiting the Teahouse.

I recently uploaded numerous files to wikimedia commons and then noticed that I consistantly misspelled one of the words in the names.

Do I have to reload each file again with the correct spelling and then nominate the old files for deletion?

Or is there an easy way to correct the spelling?

And if not, maybe there is an easy way to make a copy of each file with a new name and thhen nominnate the old files for deletion.Constant314 (talk) 19:24, 20 December 2010 (UTC)

Fixing now for you using rename template. -- DQ (t) Merry Chrismasand a Happy New Year! 19:44, 20 December 2010 (UTC)

Thank-you very much. How long does it usually take for the renaming process to complete?Constant314 (talk) 20:28, 20 December 2010 (UTC)

Watchlist etc[edit]

Re your question, I use a the watchlist (click "my watchlist" top right corner of screen) and have my preferences set to add any page I edit. See Help:watching pages for more information. You can also set up an RSS feed for selected pages - see Wikipedia:Syndication.

Redlinks arise when a wikilink is made to a page that does not exist. If you copied an existing table with links to the units and then changed the units, that would explain the redlinks. You named units that do not have a page.

Hope that helps. SpinningSpark 14:36, 21 December 2010 (UTC)

Yes, that helps, thank you.Constant314 (talk) 15:10, 21 December 2010 (UTC)

What Wikipedia is not[edit]

Just been looking over your recent work in attenuator (electronics). This is good stuff, but I have a couple of comments. Firstly, most of the component calculation information is probably better off in the individual articles for specific attenuator circuits. Indeed, there seems to be some duplication. You could put a summary in the attenuator article and use the {{main}} template to link to the details. Secondly, I would like to draw your attention to the WP:NOTTEXTBOOK policy. Wikipedia is not meant to be a textbook teaching the subject and lengthy formula derivations are getting close to being in breach of this. You might want to consider whether some of your material is more suitable for the sister project Wikibooks. Wikibooks can be linked into a Wikipedia article with the {{Wikibooks}} template. SpinningSpark 12:21, 24 December 2010 (UTC)

thank you for your comments. I will consider them carefully, but maybe not until tomorrow. Merry Christmas and thanks for the help and advice in the past.Constant314 (talk) 23:46, 25 December 2010 (UTC)
Happy holidays. I have removed the examples and derivations. The article should be much less like a text book now. As for where to put the information, I have pondered this and come up with a dilemma. There is a lot of overlap between T-pad and pi-pad. It is not a matter of effort; it is just a question of how to organize the information. Should it be in two or three places or should it be in one place with links to it in other articles? The problem with having it in two articles is that improvements, error correction, additions may be made in one article and not the other. So, I'd rather just put it in one place and attenuator looked like a good place since it treats T-pads and pi-pads equally. I got advice on this from Dicklyon who suggested " Don't make a new article that overlaps the other two; it's better to merge all into one of the existing ones, move it to Impedance matching pad or something like that, then convert the others to redirects. " I thought attenuator would be a good candidate for something like Impedance matching pad . As always I appreciate your comments.Constant314 (talk) 15:00, 27 December 2010 (UTC)
Dicklyons solution is workable, but personally, I like to see the details of specific circuits in their own articles. The general article is less hard going for the reader that way. Another possible approach is to write the common material in the template namespace and then transclude it into both articles. This would solve your problem of maintainability since any change will automatically be reflected in both articles. If you go down this path, make sure the first line of the template is a heading as this will make for easy editing of the section. SpinningSpark 23:17, 28 December 2010 (UTC)
That sounds good. Can you point me to an example?Constant314 (talk) 14:13, 29 December 2010 (UTC)
If you take a look at Talk:Aboriginal Memorial you will see that there is a GA review going on. The review can be seen on the talk page, but is actually on a different page, Talk:Aboriginal Memorial/GA1. If you look at the talk page in edit mode you will see that the review page is transcluded on to it by writing the page between double curly braces like so {{Talk:Aboriginal Memorial/GA1}}. Note that the review can be edited as if it were a section of the talk page because it begins with a heading. In the article space, pages which are to be transcluded in are placed in the "template" namespace. In those cases the namespace "template" can be omitted as "template will be assumed if nothing is specified, see for instance Heartbreak Hotel which has a list of {{Elvis Presley singles}} at the bottom of the article which also appears in many other articles. SpinningSpark 23:47, 29 December 2010 (UTC)
I think I understand that. Is the page to be transcluded just an ordinary page? Constant314 (talk) 14:57, 30 December 2010 (UTC)
Yes, any page can be transcluded on to any other page, but it is the convention to put the page to be transcluded in the template namespace rather than the main namespace because the latter is reserved only for self-contained articles, not fragments. SpinningSpark 16:36, 30 December 2010 (UTC)

File:Magnetic Vector Potential Circular Toroid (now in svg format)[edit]

png form.

I was recently editing Talk:Magnetic potential , and ran into your original and excellent image! If its ok - I redrew it in SVG form, I like your originality so kept all the colours and everything (except maybe some shading for the toroidal core, as I couldn't quite get it to work, maybe I can edit this with inkscape later, sorry)...

It has replaced the jpeg version in the article, and also noted on the talk page of that article. Thanks, =) F = q(E+v×B) ⇄ ∑ici 20:17, 26 May 2012 (UTC)

thanksConstant314 (talk) 05:45, 27 May 2012 (UTC)
One point - I didn't just edit the talk page of magnetic potential, but the article also (not sure why you changed the link back but it doesn't really matter...).
You have a user page of ~ 78kB. To significantly reduce the byte count and allow the page to load up quicker, for all the fab images you created/uploaded, you could create subpages for each section of them, say
User:Constant314/Two Ports images containing the section User:Constant314#Two Ports images,
User:Constant314/Torroidal Inductor/Transfotmer and Magnetic Vector Potential images containing the section User:Constant314#Torroidal Inductor/Transfotmer and Magnetic Vector Potential images,
User:Constant314/Toroidal Transformer Presentation images containing the section User:Constant314#Toroidal Transformer Presentation images,
etc (to name a few), and then under the sections on your user page, you just insert the subpages like a template (subpage name in curly brackets), say
{{User:Constant314/Two Ports images}},
{{User:Constant314/Torroidal Inductor/Transfotmer and Magnetic Vector Potential images}},
{{User:Constant314/Toroidal Transformer Presentation images}}, etc...
(though correct the spelling errors first to prevent page-moving things after). It may also help reduce vandalism, since editors coming to your main page will not be able to edit the contents of the subpages because they are elsewhere. Thanks again for the good work. F = q(E+v×B) ⇄ ∑ici 13:08, 28 May 2012 (UTC)
Actually, I did not do anything. Perhaps someone else changed it back? It turns out that I cannot read and display *.svg files so I guess I am glad it changed back.Constant314 (talk) 15:53, 28 May 2012 (UTC)
It's evident from this edit that you did. Again - its not important, lets forget it please. F = q(E+v×B) ⇄ ∑ici 21:18, 28 May 2012 (UTC)
It is important because I have no idea how it happened.Constant314 (talk) 02:05, 29 May 2012 (UTC)

Your comments to Kevin aylward[edit]

I noticed that you have made a very long reply to Kevin aylward at Talk:Transformer. I don't know if you were aware, but I blocked him earlier today for edit warring so he won't be replying to you any time soon unless he chooses to repent. I have taken issue with you on one of your comments, but I am avoiding expressing an opinion in the debate in general as this would compromise my position acting as an administrator as I would no longer be uninvolved in the dispute. SpinningSpark 18:01, 30 December 2012 (UTC)

I have no arguement with your comment; I'm still learning the rules. I understand that if something were absolutely wrong that it should be removed, even if a majority of the editors believed it correct. But please elaborate, if something were absolutely wrong, yet a majority of the editors believed it to be true, who would decide?Constant314 (talk) 18:38, 30 December 2012 (UTC)
In ideal cases, with editors that are behaving collaboratively, and not editing from some pre-conceived POV, there is no reason that content disputes should not be settled by examining sources. For protracted cases amongst good faith editors there are a number of dispute resolution processes available. In non-ideal cases where dispute resolution has failed and there is an issue with editor behaviour that cannot be dealt with by administrator action, it might ultimately end up at ArbCom although you don't want to go there unless you actually like interminable psuedo-legal proceedings. There is no ultimate authority for settling content disputes, the whole thing basically relies on maintaining a collegial atmosphere (and removing those editors who won't play by those rules). SpinningSpark 19:49, 30 December 2012 (UTC)
Actually, I will respond to your comments on the talk page of that article. I hope to paraphrase my understanding of your explanation.Constant314 (talk) 18:55, 5 January 2013 (UTC)

Numbering equations[edit]

This help request has been answered. If you need more help, place a new {{help me}} request on this page followed by your questions, contact the responding user(s) directly on their user talk page, or consider visiting the Teahouse.

I have a question about numbering equations. This is normally done in text books so that you can easily refer to a particular equation, yet it does not seem to be the style for Wikipedia pages to have equations numbered. So my questions are: 1. Is numbering of equations undesirable? 2. Is there a preferred way to number equations? 3. Is there an article that uses numbered equations that illustrates the practice? Thanks in advance to anyone who answers my questions.Constant314 (talk) 17:54, 9 February 2014 (UTC)

An interesting question, which I thought would be easy to answer. First, I looked at Wikipedia:Manual of Style/Mathematics; drawing blank there, I went to WP:WikiProject Mathematics and picked a few featured articles and good articles from the list on their page, to try to find examples of equation numbering. No luck. I will leave the "helpme" in case some one else can answer; also, I will post a note on the WikiProject's talk page. JohnCD (talk) 22:41, 9 February 2014 (UTC)
I don't know of an article that uses numbered equations, but the templates {{EquationNote}} and {{EquationRef}} can be used for that purpose. You may want to ask at WT:WikiProject Mathematics on whether equations should be numbered - personally I'd try to avoid numbered equations if at all possible. Huon (talk) 22:50, 9 February 2014 (UTC)
There's also {{NumBlk}} which lets you layout a line containing a formula and number. --JohnBlackburnewordsdeeds 23:49, 9 February 2014 (UTC)
To see this all in action, take a look at Poisson summation formula.--LutzL (talk) 00:16, 10 February 2014 (UTC)
Equation numbering is described in Help:Formula#Equation numbering. --Mark viking (talk) 01:09, 10 February 2014 (UTC)
Note that—with the new MathJax—anyhting appearing outside the math tags will destroy the new formula centering feature. That means that (unless the numbering is done in the math itself) numbered equations will remain left justified with the number on the far right, whereas unnumbered equations will get centered. See indeed Poisson summation formula. Ugly. - DVdm (talk) 08:07, 10 February 2014 (UTC)
  • Indentation, numbering or equation bullets: In many cases, an equation is merely indented by a lead colon ":" (or two "::"), while numbered equations would imply an expectation of mentioning the equation numbers in other text. Unfortunately, the math-tag text is often heavy, dark, bolded text and looks "unprofesssional" for extra numbering/wording, such as "where x is the angle of incidence" or similar. For numbering, I would recommend simply placing an indented plain-text number ":1.&nbsp;" in front of the math-tag for equations which will be mentioned in the text. Lists of equations should generally use asterisk bullets (":*") to allow some to wrap as two math-tags on two lines. However, beware how the math pages are the most difficult to update, often reverted with bickering or complaints by other editors, and hence, the math pages are some of the most backward, cryptic, or awkward of all WP articles, with excessive technical structure and too little explanation of the related concepts for general readers. Those pages also tend to "dog-pile" tangent topics as crammed into over-large pages with excessive obtuse abstract wording, rather than move the related tangent topics into smaller concise subpages as often done with mainstream topics. If you are a teacher or have a degree in mathematics, as I do, then I suggest working on math pages at Simple English Wikipedia, to clarify concepts for general users, and then if someone complains why the WP math pages are so convoluted, unkempt or confusing, then direct them to read about a clarified topic at Simple WP instead. -Wikid77 (talk) 22:04, 16 February 2014 (UTC)

Protocol for Replacing an Image[edit]

This help request has been answered. If you need more help, place a new {{help me}} request on this page followed by your questions, contact the responding user(s) directly on their user talk page, or consider visiting the Teahouse.

A long time ago I created the drawing file Magnetic Vector Potential Circular Toroid.jpg. This was before I knew that other formats were preferred. Another editor redrew the file an posted it as an svg file and changed some of the usages to the svg file. However, he was unable to render certain details so I recreated the image as a png file. I am unable to generate svg files. I have changed all the uses of the jpg and svg files over to the png file. I have requested deletion of my own jpg file so that it won't get accidently used again. I would also like to insure that the svg file does not get used again because it is missing certain details and I cannot maintain it or improve it. So, my question is: is it legitimate to ask for the deletion of another person's file if that file has been superseded?Constant314 (talk) 16:51, 1 March 2014 (UTC)

This is more of a Commons question than one about Wikipedia, and you have already nominated the image for deletion over at the Commons. Deleting outdated versions of images seems legitimate to me, but I'm no expert on preferred file types. Have you tried asking F=q(E+v^B), the creator of the .svg, to improve his version? Huon (talk) 17:35, 1 March 2014 (UTC)
Thanks for your reply. Yes I did leave a request on F=q(E+v^B) commons page but since then I found that his Wikipedia page redirects to User talk:Z = z² + c which has a huge banner at the top that says he/she has terminated his/her activities and permission is granted to revert any and everything he/she every contributed. So I went ahead with the deletion request.Constant314 (talk) 17:47, 1 March 2014 (UTC)

Energy sucking antennas[edit]

Nope, wasn't me. My professional life was spent mostly in the "welding industry", specifically designing control systems and power supplies for plasma-cutting torches, the differences being, for plasma cutting, dangerously-high open circuit voltages (300-400 volts), higher powers (up to 100's of KW), and the use of high-voltage, high-freq (e.g. 3 MHz), high-powered spark-gap oscillators to emit pulses that arc-and-spark (start) the torches -- the resulting EMI is beyond belief, so I have a lot of experience "hardening" electronics against EMI. That's about as close to "energy sucking antennas" as I've come. Bill Wvbailey (talk) 21:29, 3 June 2014 (UTC)

thanks for the reply.Constant314 (talk) 21:36, 3 June 2014 (UTC)

Magnetic vector potential[edit]

I'm not familiar with this notion, but perhaps the following reference will help. (I see what you mean about the cost of these books! But we're in luck . . ..) Many years ago I bought a book called "The J & P Transformer Book" by Martin Heathcote, first published in 1925 and now in its 13th or so edition. This book belonged to and stayed with the company where I worked, but marvel of marvels it's gone into the public domain, all 950+ pages of it, and I was able to download all of the 12th edition (if you google "J & P Transformer Book" you'll find this as the second result):

In the first chapter you'll see quite-complicated, thorough phasor diagrams (these have flux and voltage and currents etc all on the same diagram). The pdf version is a bit marred by poor resolution of these drawings (most seem adequate), but check out Appendix 7 "The use of finite element analysis in the calculation of leakage flux and dielectric stress distributions" where you'll find some really fancy math and physics . . . div and curl and all that good stuff. Ditto for some of the other Appendices.

Is this the sort of thing you're after? I hope this helps . . . Bill Wvbailey (talk) 14:11, 4 June 2014 (UTC)

Electric potential[edit]

The clause you removed is adequately covered at the top, where it is explained that the point charge must be divided out. It's perfectly reasonable to remove it from the general statement in the introduction, so I left it as you edited it. Thanks. Redheylin (talk) 11:53, 18 February 2015 (UTC)
