A voltage source creates a difference of electric potential between its terminals; its replacement, a short circuit, equalizes potential.

Inschakelstromen pdf file, in Dutch. Put new text under old text. Basis elektriciteit in Dutcheen tip. Therefore R1 is in an open circuit by itself, so the voltage must be the same on both sides of R1 because of Kirchhoff’s Voltage Law.
I also assume that this would work with impedances given that the voltage source would be sinusoidal in some way like omegatron said. Please comment accordingly about these proposed changes. Proceedings of the IEEE.

Why say only for courss single frequency? For generalized impedances, the non-resistive parts are apparently folded into the voltage source, so the voltage is a function of frequency. Determine V oc as teh open-circuit voltage of A with B disconnected.
Analysis of Electric Circuits. Then the equivalent circuit of A is a source voltage V oc in series with R 1 where R t is thevnein resistance at the terminals when all the independent sources are de-activated. The article has recently had added a proof by Cramer’s rule. I believe the example is wrong — according to my calculations, Vth should be Comments on my pretty large changes?

Albert Einstein is notable, Garfield is notable, but a mention of Einstein in a Garfield strip would certainly not be notable, and would not be in the Einstein article.
The statement of the theorem results immediately from this definition. Why in the current example picture is R1 ignored when calculating the Vth? I think that condition should be changed in the article as its a bit misleading. Ask questions, get answers. Can you please express this in a way that a non-initiate will understand without a lot of additional and unnecessary searching?
Doubtless Cramer’s rule can be used in a proof of Thevenin and the article can say this ideally with a suitable citation but it should not be claiming to present a proof when no proof is given.

You are probably trying to assume that the voltage at A is 0 V. Image and rest of article’s text would need revision to suit.
I vote to delete it until something better can be written. I can see where it looks like R1 was ignored.

I think it would be very very very helpful if this were generalized to impedances. However, it is merely stated without proof that this is the courw from using Cramer’s rule.

I was wondering if theres other equivalent circuits other than thevenin’s and norton’s – ones perhaps with capacitances and maybe inductances.
All the proofs I have seen involve examining the behaviour with added external sources, either voltage  or current . By comparison, the Norton circuit always dissipates power so it gets warm and, short of magic or perpetual motioneventually runs down.
