Most of the engineering tools we use in Computer Engineering are designed to run on Windows. If you have a Mac, the easiest way to run these windows applications is with Windows on a Virtual Machine. Here is a link to an article on how to do this for free. There are other methods and different Virtual Machine platforms but this is just one example. In this instance, google searching can produce alternative methods. Note that I do not own a mac and I have not tested this or any other methods. Windows On Mac For Free

Review / Supplemental Materials

These are recommended problems and example midterms with solutions provided to prepare for the exams. This will not be collected or graded, but many of these questions will be used for the Midterms and Final. It is necessary to get practice with these problems and it is strongly encouraged to start as soon as possible in order to have plenty of time to get help, please ask questions and prepare.

Midterm Prep

Topics: Basic Atomic Theory, Valence Electrons, Voltage, Current, Conventional vs Electron Flow, Resistance, Series Circuits, Parallel Circuits, Series-Parallel Combination Circuits, Resistance in Series & Parallel, Equivalent Resistance, Kirchhoff’s Voltage and Current Law, Superposition

pg100 Self-Test: 1-4, 6, 8-13,15,18;

pg102 Problems 3-12, 3-17, 3-18, 3-23, 3-33, 3-36 (Please Draw one schematic for each set)

pg132 Self-Test: 1-9,12-17; Problems (Don’t use Multisim if asked for, solve by hand): 4-2, 4-6, 4-11 , 4-16, 4-17, 4-18, 4-29 (answer c in conventional flow), 4-30 (answer c in conventional flow), 4-34, 4-39

Pg194 Questions 1 to 12 pg196 6-1 to 6-32 skip 6-26, 6-27 (Don’t use Multisim if asked for, solve by hand)

Lab 5 – Thevenin and Norton Equivalent Circuits


Lab 6- Introduction to LTSpice and Capacitors


Lab 7 – Mesh Analysis


Online: For Lab 6 we have a few limitations. We will skip the breadboarding as the myDaq is not capable of providing the 2 separate voltages we need. We will also skip the soldering portion of this lab for safety and supply reasons. Normally during an in-class session I would be providing soldering irons and prototype board to construct the prototype. This is not possible to do remotely so I’ll ask everyone to skip this.

Deliverables for the Online version. Solve the circuit by hand using mesh analysis and solve for Voltage and Current of each component (the 3 resistors). Create an LTSpice model of the circuit and find Voltage and Current for each component. Create a table comparing your solution to the results from LTSpice.
