What does the Thevenin equivalent circuit of an AC circuit consist of?
The equivalent circuit consists of a constant voltage source and a single series resistor called the Thevenin voltage and Thevenin resistance, respectively. Short all voltage sources and open all current sources.
Is the output same after replacing the circuit by its Thevenin equivalent?
Replacing a network by its Thevenin equivalent can simplify the analysis of a complex circuit. In this example, the Thevenin voltage is just the output of the voltage divider formed by R1 and R3. The Thevenin resistance is the resistance looking back from AB with V1 replaced by a short circuit.
What are the methods of determining Thevenin resistance?
The different methods of finding Thevenin’s Resistance or internal impedance are as follows: For Independent Sources – The most common method of finding the equivalent Thevenin’s Resistance (R TH) or the internal impedance of any linear, bilateral network containing independent current or voltage source is to deactivate the source by its internal resistance .

load resistor (Fig 2).
What are the advantages of using Thevenin theorem?
Thevenin’s Theorem is only useful for determining what happens to a single resistor in a network: the load. The advantage, of course, is that you can quickly determine what would happen to that single resistor if it were of a value other than 2 Ω without having to go through a lot of analysis again.
