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
steadystate analysis, and then further develops these concepts in the analysis of single and threephase
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 4lab 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
engineering graph paper. Others are links to online electronicallygraded problems that are due 10 minutes prior to
the start of class  make sure you have saved your work by then.
You must register with the Connect system to complete the
online EAssignment problems
