Unformatted text preview: er circuit. At the point of interface, each sub‐circuit is seen as a two‐terminal circuit (one‐port circuit). Such two‐terminal circuits can be replaced by an equivalent circuit consisting of a source and a resistance. This can be a voltage source with a series resistance or current source with a parallel resistance. The two equivalent circuits are known as Thevenin and Norton Equivalent Circuits respectively. Thevenin’s Equivalent RL RL The Thevenin equivalent of a two‐terminal circuit is represented by a voltage source in series with a resistor. The value of the voltage source is the open circuit voltage of the circuit between the two terminals. Looking at the Thevenin’s equivalen circuit, if nothing is connected between the two terminals, there will be no current flowing. Hence voltage drop across the resistor RT will be zero. The voltage across the terminals then is the Thevenin voltage for the circuit. VT Voc If there are no independent sources in the circuit then the value of t...
