EE40, Midterm #1, Spring 1994 Problem 2 (20 points) You are to analyze the following dc circuit using node analysis. There are four unknown node voltages, VA, VB, VC, VD. Assume IA, IB, IC, V1, V2 (and R1, R2, R3, R4, R5, and u) are all known. You must therefore write four independent equations (in the appropriate space on the following page) sufficient to solve for the four voltages. DO NOT SOLVE. Problem #3 Problem 3 (20 points -- 4 points for each of 5 parts) Find the voltage Vx or current Ix which would be read by the ideal voltmeter of ammeter. Hint: Nodal analysis is not needed and will take too much time. There will be no partial credit on this problem!

### 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.
