Thevenin's Theorem Example. Let us understand Thevenin's Theorem with the help of an example. Example: Step 1: For the analysis of the above circuit using Thevenin's theorem, firstly remove the load resistance at the centre, in this case, 40 Ω. Step 2: Remove the voltage sources' internal resistance by shorting all the voltage sources connected to the circuit, i.e. v = 0. Détermination du modèle de Thévenin. Soit un circuit composé de plusieurs sources et de plusieurs résistances possédant deux bornes A et B entre lesquelles est raccordée une charge : U T h {\displaystyle U_ {Th}\!} est la tension calculée ou mesurée, entre les bornes A et B lorsque la charge est déconnectée (tension à vide). Introduction. In this tutorial, we present a powerful method that can simplify through some transformation steps, complex circuits into elementary circuits and this method is commonly known as Thevenin's theorem.. Originally, it was the German physicist Hermann von Helmholtz who first demonstrated the theorem in 1853, but history kept the name of the French engineer Leon Thevenin, who in Thevenin's theorem states that all linear circuits can be simplified to an equivalent circuit with a single voltage source in series with a single resistor connected to a load. Step 1: Remove the load resistor and replace it with an open circuit. Step 2: Calculate the Thevenin voltage—the voltage across the open circuit. Steps to calculate Thevenin's equivalent circuit. Remove the load resistance. After short circuiting all the voltage sources and open circuiting all current sources, find the equivalent resistance (R th) of the circuit, seeing from the load end.; Now, find V th by usual circuit analysis.; Draw Thevenin's equivalent circuit with V th, R th and load.
