The emf of the voltage source is the open circuit emf at the network terminals, and the series resistance is the resistance between the network terminals when are sources are set to zero.Suppose we are given an arbitrary circuit containing any or all of the following elements: resistors, voltage sources, current sources (the source can be dependent as well as independent).

Hence, the thevenins voltage or voltage across the load resistance terminals which is open circuited can be determined using above mentioned laws (Ohm’s law and Krichhoff’s law) and are tabulated in a tabular form as shown below: Then, the circuit can be represented as shown in the figure below with voltage across open load terminals, resistances, and current in the circuit.
This voltage across the open load resistance terminals is termed as thevenins voltage which is to be placed in the thevenins equivalent circuit.
Then, share your views, comments, ideas, and suggestions in the comments section below.
Any two-terminal network containing resistances and voltage sources and/or current sources may be replaced by single voltage spruce in series with a single resistance.
His keen interests include Electronics, Electrical, Power Engineering.
Engineering in electrical and electronics stream is comprised of several engineering subjects that includes basic topics such as laws like Ohm’s law, Kirchoff’s law, etc., and network theorems These laws and theorems are used for solving the complex electrical circuits and mathematical calculations to find out network parameters such as current, voltage, and so on in electrical network analysis.
Here, in this circuit is equivalent to the above circuit (with V1, V2, R1, R2, and R3) in which the load resistance R2 is connected across the terminals of thevenins equivalent circuit as shown in the circuit below.
Now, how to find out the values of thevenins voltage and thevenins resistance?
As we know that, based on the load conditions the load resistance is accordingly varied and thus, the total resistance has to be calculated based on how many resistors are connected in the circuit which is very critical.
So, to make it easier thevenins theorem states that the load resistor has to be removed temporarily and then calculate the circuit voltage and resistance by reducing it to a single voltage source with a single series resistor.
