Electrical Circuit Analysis is one of the most fundamental subjects of Electrical
Engineering which is taught in two courses in successive semesters under the names
of “Electrical Circuit Analysis I” and “Electrical Circuit Analysis II” or under the
names of “DC Electrical Circuit Analysis” and “AC Electrical Circuit Analysis” in
universities and colleges all over the world. This textbook, like the previously
published DC Electrical Circuit Analysis, includes basic and advanced exercises of
AC Electrical Circuit Analysis with very detailed and multiple methods of
solutions. The textbook can be used as a practicing textbook by students and as a
supplementary teaching source by instructors.
To help students study the textbook in the most efficient way, the exercises have
been categorized in nine different levels. In this regard, for each problem of the
textbook, a difficulty level (easy, normal, or hard) and a calculation amount (small,
normal, or large) have been assigned. Moreover, in each chapter, problems have been
ordered from the easiest problem with the smallest calculations to the most difficult
problem with the largest calculations. Therefore, students are suggested to start
studying the textbook from the easiest problems and continue practicing until they
reach the normal and then the hardest ones. On the other hand, this classification
can help instructors choose their desired problems to conduct a quiz or a test.
Moreover, the classification of computation amount can help students manage their
time during future exams and instructors give the appropriate problems based on
the exam duration.
Since the problems have very detailed solutions and some of them include multiple
methods of solutions, the textbook can be useful for the underprepared students. In
addition, the textbook is beneficial for knowledgeable students because it includes
advanced exercises.
In the preparation of problem solutions, use of typical methods of Electrical Circuit
Analysis has been tried to present the textbook as an instructor-recommended one.
In other words, the heuristic methods have never been used as the first method of
problem solution. By considering this key point, the textbook is in the direction of
instructors’ lectures, and the instructors will not see any untaught problem solutions in
their students’answer sheets.
The Iranian University Entrance Exams for the Master’s and PhD degrees of
Electrical Engineering major is the main reference of the textbook; however, all the
problem solutions have been provided by me. The Iranian University Entrance Exam
is one of the most competi- tive university entrance exams in the world that allows
only 10% of the applicants to get into prestigious and tuition-free Iranian
universities.
