✓ Plot the load resistance versus the power across it to show the maximum value and
location of power.
Now build Thevenin's equivalent circuit and find the current and voltages while varying
load resistance value.
✓ Fill table 2.

Lab #7: Thevenin's theorem applications
Objective:
This lab is done to better understand one of the fundamental theorems of electric circuit, the
Thevenin's theorem and its usage. We implemented it using some applications to understand it
thoroughly.
Theory:
According to Thevenin's theorem, we can replace power sources having load terminals and the
resistive elements by an ideal voltage source having a series resistance called Thevenin's
equivalent circuit. The voltage source is called Vth (pen circuit voltage across nodes) while the
resistance is called Rth (open circuit resistance across nodes). Another parameter involved in
the calculation is Isc which is the short circuit current across nodes.

Part II: Mesh analysis:
Now we will perform the loop analysis of the same circuit. We can see that the circuit contains
three loops solved in the clockwise direction to find the voltages and currents. The values are
then compared to that obtained by nodal analysis. We then completed the table below.

Analysis:
Both the methods have their own advantages. It is better to use a mesh circuit analysis when
the circuit more nodes than meshes and if the circuit has more meshes than nodes than nodal
analysis is preferable.

Lab #6: Nodal and Loop analysis
jective:
is experiment is performed to thoroughly understand the two most commonly used types of
cuit analysis; nodal and loop (mesh) analysis.
eory:
e nodal analysis is a most commonly used application of Kirchhoff's voltage and current laws
nd ohms law. In nodal analysis, the voltage is measured between a desired point (node) and
e reference point. The reference point is usually the ground or any other node of known
oltage. Then we apply nodal analysis on the circuit using KCL.
he mesh analysis is the other technique use for circuit analysis. First of all a loop for the flow
f current through the circuit is identified. Then after assigning mesh current, we apply KVL and
olve the equations.
Equipment used:
Voltage supply
Analog discovery device
Resistors
ord
dal analysis and the other for mesh analysis.
