Unformatted text preview: ECE201 Lect-13 1 Thvenin's Theorem (5.3, 8.8) ECE201 Lect-13 2 Thevenins Theorem Any circuit with sources (dependent and/or independent) and resistors can be replaced by an equivalent circuit containing a single voltage source and a single resistor. Thevenins theorem implies that we can replace arbitrarily complicated networks with simple networks for purposes of analysis. ECE201 Lect-13 3 Implications We use Thevenins theorem to justify the concept of input and output resistance for amplifier circuits. We model transducers as equivalent sources and resistances. We model stereo speakers as an equivalent resistance.
