# Thevenin Theorem Example with Step by Step Solution

*Statement: Any linear bilateral electrical network can be reduced to a single voltage source and a series resistors.*

Thevenin theorem is a useful network theorem which helps us to reduce a complex electrical network to a simple circuit. Thevenin theorem reduces a circuit to simple series circuit thus making the analysis process very easy for circuits. Let’s understand the theorem:

Steps involved in solving circuits:

- Remove the load (if any) from the circuit.
- Label the resulting terminals.
- Replace all the voltage/current sources.*
- Calculate the equivalent resistance of the circuit. This resistance is known as Thevenin resistance.
- Determine the output voltage across labeled terminals.
- Connect resistance (from step 4) in series to a voltage source (whose value equals the value calculated from step 5).

* A voltage source is replaced by a short circuit, whereas the current source is replaced by an open circuit.
