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 at the
link in the paragraph below, which also grants you two years
of access to the online text. The last page of the
bookstorebought text gives code to register with Connect;
you can also purchase electronic access to the text with a
Connect code immediately through this
link.
All Connect assignments are available at
