EE223: Circuits II

EE223, Electrical Circuit Analysis II, is the second course in a series designed to provide engineering majors the tools to analyze and design passive analog circuits. This course introduces capacitors and inductors, and develops the natural and forced responses of circuits containing these elements. It introduces complex phasor notation in the context of sinusoidal steady-state analysis, and then further develops these concepts in the analysis of single and three-phase AC power. The laboratory portion of the course introduces the practical skills of designing, building, and debugging physical circuits in the context of relevant contemporary examples. It includes a major design 4-lab sequence in which cadets design and build a project of their choice. Prerequisite: C or better in EE 122. Corequisite: MA311. (3 lecture hours, 2 lab hours, 4 credit hours).


Lecture Schedule

In the following table, the readings and homework are assigned on the day listed and due on the following lesson. Some problem sets are downloaded below and completed by the student on graph paper. Others are links to online electronically-graded problems that are due 10 minutes prior to the start of class - make sure you have saved your work by then. The e-text, which is bundled with access to the online problems, is required and is available here for $60. If you prefer a printed text in addition, it is available in the bookstore.
