Homework 2


Date Assigned: Wednesday, August 31, 2011
Date Due: Wednesday, September 7, 2011

  1. Reading: In the Ulaby/Maharbiz text, please continue to study Chapter 2, Sections 2-1 through 2-4, and also study Sections 2-5 and 2-6. I suggest you read Section 2-7 but we will not discuss it in class. Also, please begin studying Section 3-1 on the Node-Voltage Method. (However, we probably will not begin Chapter 3 until the week of Sept. 12.)

  2. I suggest that you install the Multisim 11 software that came with the textbook on your computer, and run through the examples in Section 2-8. Nothing needs to be submitted, but work through the examples to become familiar with the software. Please note the similarities and differences between Multisim and the PSpice software (by OrCAD) that we use in the lab. (You will need to wait until we do Lab 1 on Sept. 8 to do this comparison.)

    You may want to become familiar with both versions of PSpice (Multisim and OrCAD). The OrCAD version will be used in lab and in your future courses, while Multisim will be available on your own computer. You will always be free to use either OrCAD or Multisim for assignments in this course.

  3. Please solve the following problems in Chapter 2 of the textbook and submit solutions in class on Wednesday, Sept. 7.
    Problems 2.14, 2.16, 2.22, and 2.23: All of these can be solved with Ohm's Law, KVL, and KCL without solving simultaneous equations.
    Problems 2.26, 2.28, 2.33, and 2.34: Solve these by combining series/parallel resistors and look for voltage/current dividers. We will do some similar problems in class on Monday, Sept. 5.
    Problem 2.29: Use source transformations (again we will do a similar problem in class on Sept. 5).
Thank you and have fun.
