Lab # 8: THEVENIN EQUIVALENT CIRCUIT
Introduction
This laboratory experiment will help the students to verify the concept of Thevenin Equivalent
circuits for a given resistive circuit.
Objectives
1. Verify the Thevenin’s theorem through an experiment.
2. Find the R
TH
by various methods and compare values.
Conduct of Lab
The students are required to work in groups of three to four; each student must attempt to
understand and use the laboratoy set-up and conduct at least one or two parts of the requirement
experimentation. The lab engineer will be available to assit the students.
In case some aspect of the lab experiment is not understood the students are advised to seek help
from the teacher or the assigned Lab Engineer.
Lab Equipment
The following equipment would be used in this experiment:
 Breadboard
 The Multimeter
 The Power Supply
 Multimeter
 Circuit components
Overview:
Thevenin’s theorem states that any linear two-terminal circuit (Fig. 1a) can be replaced by an
equivalent circuit (Fig. 1b) consisting of a voltage source V
TH
in series with a resistance R
TH
where
 V
TH
is the open-circuit voltage at the terminals, and
 R
TH
is the equivalent resistance seen thru the terminals provided that all the independent
