,Preface
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.
