Talk:Output impedance

message: There is no clear explanation of what internal resistance is. I'll try and find the source we used in my AS physics classes, where it was modelled as a resistor within the battery, so to speak ... 172.202.214.197 14:48, 19 February 2007 (UTC)
replies: text: It's kind of hard to explain.  Any real device that creates electricity can be modeled as a perfect voltage or current source and some impedance in series with it.  That's probably too technical.   — Omegatron 23:53, 19 September 2005 (UTC)

text: I think it's useful to introduce the concept of generator superposition theorem, then we can use a fictive voltage source, then measure the current, then divide voltage over current. Correct me if I'm wrong.  — Preceding unsigned comment added by Diraniyoussef (talk • contribs) 19:08, 17 January 2021 (UTC)

thread_title:  internal resistance 

message: No attempt to even connect this to chemistry (especially in batteries, with concepts such as polarization of the electrodes perhaps)

thread_title:  CHEMISTRY 

message: The article never uses the term "output impedance". It does use "internal resistance" repeatedly. So why is the article called "output impedance" with a redirect from "internal resistance"? Shouldn't it be the other way around?

thread_title:  Output impedance 

message: The article says, "it is impossible to directly measure the internal resistance of a battery."  But, it is impossible to directly measure the resistance of any device.  Resistance is always measured as a ratio of (change in) voltage to (change in) current.  What the author probably meant to say, is that an ohm meter (or the ohms setting on a multimeter) can not be used to measure the resistance of a battery because such meters are designed with the assumption that the only voltage source in the test circuit is the source contained within the meter itself.  Such meters do not correctly account for the open-circuit voltage of the battery.

thread_title:  Measuring the "internal resistance" of a battery. 

message: Initially this article contained material on internal resistance, which was wrong because Output Impedance is not internal resistance. So, I had shifted the article to Article "Internal Resistance"
The output impedancec article should eventually look like the input impedance article. I had asked to delete it until someone creates it, but it was rejected and redirected back to internal resistance. Then I had to add the single-line-definition to remove the wrong re-direct. Now people want to transfer it to wikitionary!!!!!! Nobody is bothered to build the article. They only want to bully upon... —Preceding unsigned comment added by Vayalir (talk • contribs) 
:Instead of attacking other editors, and reverting with edit summaries about Wiktionary, why didn't you just leave it until you could build an article? You could have built in in your webspace with references if you couldn't do it on your own PC. That would have been a trouble-free way to do it. How about adding some content here -- on this page, to see what you think it should look like? Dougweller (talk) 17:50, 3 April 2009 (UTC)
thread_title:  Problem 

message: I don't understand this discussion of moving this article to wiktionary. It's an important concept in electronics, and should be in Wikipedia. I've done some improvements and enlarged the article somewhat. But it's still a stub, we need more help. And please help me correct things which I may have misunderstood – I'm not an expert, but I know some. Mårten Berglund (talk) 20:06, 3 April 2009 (UTC)
replies: text: That's great. As a definition, it didn't belong here. As an article, it does. Now it is more than a definition. Dougweller (talk) 21:07, 3 April 2009 (UTC)
replies: text: Thanks. If someone could fix a figure, would be nice though. Mårten Berglund (talk) 00:44, 4 April 2009 (UTC)

text: I'm not an expert, but isn't it possible to view every circuit as a Thévenin circuit with a voltage source and an internal resistance? However, feel free to correct things that you believe is incorrect. Mårten Berglund (talk) 11:58, 10 April 2009 (UTC)
