EE 201 Lab3 Tian Gu Code:721 Team partner: Tielong Su Chaojun Zhang Introduction     :    In the first part of this lab, we got the results from our calculations by  using mesh current and node voltage techniques, Pspice and our measurement from  the circuits. And we compared them to make sure each of these methods would work.  And the second part is mainly a proof of using Thevenin equivalent circuit . Part1: Node voltages, mesh currents, and superposition We use the mesh current and node voltage techniques to get the currents and resistors  in the first circuit, i1=3.082e-3A i2=4.389e-3A i3=3.219e-3A VR=3.2188v And we also checked the answers by using pspice.

We got the same results as our calculations. So then we built the circuit and got the  measurements. First we measured all the resistor values: R2.2=2.105k Ω   R4.7k Ω =4.679k Ω   R4.7right=4.6828k Ω   R1000=0.989k Ω   R3.3=3.278k Ω So we found the percentage difference is smaller than 5%. So we kept working on the

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
