Wikipedia English - The Free Encyclopedia

As originally stated in terms of DC resistive circuits only, the

**Thévenin's theorem**holds that:- Any linear electrical network with voltage and current sources and only resistances can be replaced at terminals A-B by an equivalent voltage source V
_{th}in series connection with an equivalent resistance R_{th}. - This equivalent voltage V
_{th}is the voltage obtained at terminals A-B of the network with terminals A-B open circuited. - This equivalent resistance R
_{th}is the resistance obtained at terminals A-B of the network with all its independent current sources open circuited and all its independent voltage sources short circuited.

- Any linear electrical network with voltage and current sources and only resistances can be replaced at terminals A-B by an equivalent voltage source V
