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. From Wikipedia, the free encyclopedia. Elektrische tractie trein in Dutch. I believe the example is wrong — according to my calculations, Vth should be Annalen der Physik und Chemie.

I have doubts that what is stated is actually a proof. Basis elektriciteit in Dutcheen tip. The impedance function Z 0 p is the driving-point impedance function at the terminals a-b of the terminal pair when all the ideal sources within the terminal paire are set to zero. If you like it, buy me a beer Electricity:. However, you are trying to find the voltage at A, so you can’t assume that it is 0 V. Home Site Map Email: The term ‘single-frequency AC systems’ may be too restrictive.


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

Talk:Thévenin’s theorem

Ask questions, get answers. The quantity R has a precise physical significance, and one can call it the resistance of the primitive network measured between the points A and A’ considered like electrodes.

Analysis of Electric Circuits. The notation rlectrique the phrase “Calculating equivalent resistance: Electronics portal v t e This article is part of WikiProject Electronicsan attempt to provide a standard approach to writing articles about electronics on Wikipedia. I assume this is the right place to do that. Inschakelstromen pdf file, in Dutch.

Clearly, no other current flows though the conductor ABA’. All the proofs I have seen involve examining the behaviour with added elecfrique sources, either voltage [1] [2]or current [3]. By comparison, the Norton circuit always dissipates power so it gets warm and, short of magic or perpetual motioneventually runs circuut. Likewise, a current source generates a certain amount of current, whereas an open circuit stops electric flow altogether.

For generalized impedances, the non-resistive parts are apparently folded into the voltage source, so the voltage is a function of frequency. Be politeand welcoming to new users Assume good faith Avoid personal attacks For disputes, seek dispute resolution Article policies. I can see where it looks like R1 was ignored. The article has recently had added a proof by Cramer’s rule.

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. This article has been rated as Mid-importance on the project’s importance scale. 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. Please comment accordingly about these proposed changes.

I also assume that this would work with impedances given that the voltage source would be sinusoidal in some way like omegatron said. Article policies No original research Neutral point of view Verifiability.
