__Lab 4 - Thevenin and Norton
Equivalent Circuits __

** Objectives:** There are four main objectives in
this lab. The first objective is to
develop Thevenin and Norton equivalent circuits
analytically. The second is to build the
circuit shown in Figure 1 and its Thevenin equivalent on the breadboard and
determine that the circuits are equivalent. The third objective is below.

*Figure **1** - **Circuit diagram*

2. Find the Thevenin and Norton equivalents of the circuit in Figure 1 analytically where Vin=8V, R1=2.4 kΩ, R2=2.4 kΩ, and R3=1.8 kΩ. Breadboard the following circuit and see if your calculations are correct. (Remember to connect the black wire to ground!!) Include all work with the lab report.

3. Design the previous schematic, its Thevenin equivalent, and its Norton equivalent in Mentorgraphics and determine if the same results appear. Take snapshots of these and include them with your lab report.

4. Finally, develop
your own circuit with at least six (6) resistors and having at least two in
series and two in parallel. Find out its
parameters on the breadboard, calculate its Thevenin and Norton equivalent in Mentorgraphics and demonstrate that its terminal
characteristics are duplicated in your lab set up (by its original design and
its Thevenin equivalent). Show your lab
proctor your circuit and its Thevenin equivalent before breaking down your
setup.
