Thevenins theorem states theat “Any linear, bilateral network having a no of voltage sources and resistances can replaced by a simple equivalent circuit consisting of single voltage source in series with a resistance, where the value of the voltage source is equal to the open circuit voltage across the two terminals of the network and the resistance is equal to the equivalent resistance measured between the terminals with all the energy sources replaced by their internal resistances”.
In many pratical applications it is always not necessary to analyze the complete circuit. It requires that the voltage or current or power in only one resistance of a circuit be found. The use of this theorem provides a simple, equivalent circuit, which can be substituted for the original network.
