Talk:Millman's theorem

message: THis is the more common form of statement:
If any number of admittances Y1, Y2, Y3, ... meet at a common point P, and the voltages from another point N to the free ends of these admittances are E1, E2, E3, ... then the voltage between points P and N is:
VPN = (E1Y1 + E2Y2 + E3Y3 + ...) / (Y1 + Y2 + Y3 + ...)
VPN = SEY / SY
The short-circuit currents available between points P and N due to each of the voltages E1, E2, E3, ... acting through the respective admitances Y1, Y2, Y3, ... are E1Y1, E2Y2, E3Y3, ... so the voltage between points P and N may be expressed as:
VPN = SIsc / SY

replies: text: What I usually see in text books is even different, but it resembles more the above than the wikipedia entry itself. If someone has a good reference, please update the article. Some examples to illustrate the theorem would be useful too. Aphexer (talk) 19:51, 25 December 2008 (UTC)

thread_title:  Useful Application? 

message: I have added the original publication of Millman which can be found via the IEEE Xplore Digital Library. 
Thus, the "This article does not cite any references or sources." should be removed130.237.53.229 (talk) 09:21, 26 February 2015 (UTC)
replies: text: Yobot has now changed it to "refimprove" which is about right.  Millman's paper is the primary source, there are still no secondary sources. SpinningSpark 18:27, 3 March 2015 (UTC)
thread_title: References

message: Info from A. Jones, 21 Nov 2015: I am planning to contribute an update to this article with the following changes:-
* A rewrite of the first section, sticking to Millman's original equation and nomenclature, removing the generalisation to current sources etc, which masks the simple concept.
* A couple of sections on ways of deriving the basic theorem
* A section on generalising the theorem, presenting pretty much what is on the page today, plus clarifying the terminology.  Currently, V_k etc is used, which gets confused with the index numbers.
* A section on the dual of the theorem for current sources in series with parallel admittances across each current source.
* Some examples of usage
* Better references to key text books
Note that I have the original paper, and believe we should stick as close as possible to this.  — Preceding unsigned comment added by Amj4321 (talk • contribs) 09:46, 21 November 2015 (UTC)
replies: text: I have taken the liberty of boxing your draft text to keep it distinct from the conversation.  I'm glad to see someone is taking this article by the scruff of the neck, it's needed it for a long time.  I don't think that you should get too hung up on Millman's original paper.  Yes, it should be covered, both for accuracy and historical interest, but the focus of the article should be on the present day usage and conception of the theorem, rather than sticking rigidly to what Millman originally wrote.

thread_title:  Proposed Major Update / Cleanup 

message: I have removed some of the complications in the expression given in this article.  I am not disputing that the expression is correct, but that's not how reliable sources handle it.  I've looked in a dozen text books and they all treat only the simple case of multiple voltage sources in parallel.  The treatment of current sources can perhaps be added as an additional section.
