Homework 12


Date Assigned: Wednesday, November 14, 2012
Date Due: Friday, November 30, 2012 by 12 noon
  1. Reading: In the Ulaby/Maharbiz text, please continue to study Chapter 7, Sections 7-1 through 7-9.

    New on Nov. 29: Videos on circuits topics that follow our textbook are available at
    http://www.ntspress.com/publications/circuits-second-edition/circuits-2e-faculty-resources/circuits-videos-from-berkeleys-ee-40/

  2. Labs: We will do Lab 6 on Nov. 13 & 15, and Lab 7 on Nov. 27 & 29. Neither lab will require a formal report.

  3. Lectures: You may recall that we have one extra lecture session since we had the two mid-term exams on Fridays. The lecture on Wednesday, Nov. 28 is optional, and we will have a problem session for Homework 12. No new material will be covered, but help will be provided so that you can successfully complete all of the problems on this assignment. Your goal should be to solve Homework 12 before the class on Nov. 28, and your remaining questions will be answered on Nov. 28 (if you need the help).

    The lecture schedule is as follows for the remainder of the semester:

  4. Final Exam: The final exam will be on Monday, Dec. 10, 2012 from 8:00 - 11:00 AM, in the classroom that we meet for lectures, BRKI 066. The exam will be cumulative, closed-book and closed-notes, and you can bring one sheet of 8.5" x 11" paper with notes written on both sides. You will also need a calculator. (Formulas for Y-Delta transformations will be provided, so you don't have to include them on your formula sheet.)
    The final exam will emphasize the material in Chapter 7 (sinusoids, phasors, impedance, etc.).

  5. Please solve the supplemental problem linked here and submit your solution by noon on Friday, Nov. 30. (You should solve this problem before Nov. 21.)

  6. Please solve the following problems in Chapter 7 and submit solutions by noon on Friday, Nov. 30. (You should solve all of these problems before Nov. 21.)

  7. Please solve the following problems in Chapter 7 (Thevenin equivalent circuits, nodal and mesh analysis), and submit solutions by noon on Friday, Nov. 30. (You should solve some of these problems before Nov. 21.)
    Problems 7.35, 7.47, 7.48, 7.51, 7.52, and 7.56.
