The equivalent circuit is a voltage source with voltage Vth in series with a resistance Rth. The Thévenin-equivalent voltage Vth is the open-circuit voltage at the output terminals of the original circuit. When calculating a Thévenin-equivalent voltage, the voltage divider principle is often useful, by declaring … See more As originally stated in terms of direct-current resistive circuits only, Thévenin's theorem states that "Any linear electrical network containing only voltage sources, current sources and resistances can be replaced at … See more • Many circuits are only linear over a certain range of values, thus the Thévenin equivalent is valid only within this linear range. See more In 1933, A. T. Starr published a generalization of Thévenin's theorem in an article of the magazine Institute of Electrical Engineers Journal, titled A New Theorem for Active Networks, which states that any three-terminal active linear network can be … See more • Wenner, Frank (1926).
