http://physics.bu.edu/adlab_and_elab/input-and-output-impedance/ 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.

WebOct 1, 2015 · The Basics. Thevenin’s theorem states that any circuit composed of linear elements can be simplified to a single voltage source and a single series resistance (or series impedance for AC analysis). Norton’s theorem is the same except that the voltage source and series resistance are replaced by a current source and parallel resistance. WebIn order to apply Thevenin’s Theorem, let’s disconnect R E, as in Figure 3. We will calculate the Thevenin equivalent source of this simplified circuit. Figure 3. In Figure 3 I noted the open circuit voltage with voc. The derivation of this voltage is really simple. From R source, r ∏ and v oc loop, the v oc equation is
