EE 40, Midterm #1, Summer 1999 EE 40, Summer 1999 Midterm #1 Professor Dennis M. Sylvester Problem #1 Node Voltages Va through Vd are labeled on the above circuit diagram. Note the location of ground. a. Circle all supernodes b. Write Vx and Iy in terms of variables Va through Vd. Vx = _________ Iy = _________ c. Perform nodal analysis for the entire circuit. You should get four simultaneous equations and four unknowns. The unknowns are Va, Vb, Vc, and Vd. Simplify these equations and fill in the blanks below. Do not solve these equations. file:///C|/Documents%20and%20Settings/Jason%20Raftery/My%20Documents/UC...STS/Electrical%20Engineering%2040%20-%20Summer%201999-Sylvester-MT1.htm (1 of 6)1/27/2007 5:10:31 PM

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.

Dana University of Pennsylvania ‘17, Course Hero Intern

• 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.
