,Preface
Electrical Circuit Analysis is one o ḟ the most ḟundamental subjects o ḟ Electrical Engineering
which is taught in two courses in successive semesters under the names o ḟ “Electrical Circuit
Analysis I” and “Electrical Circuit Analysis II” or under the names o ḟ “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 o ḟ AC Electrical Circuit Analysis with very detailed and multiple
methods o ḟ 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 e ḟ ḟicient way, the exercises have been
categorized in nine di ḟ ḟerent levels. In this regard, ḟor each problem o ḟ the textbook, a di ḟ
ḟiculty level (easy, normal, or hard) and a calculation amount (small, normal, or large) have
been assigned. Moreover, in each chapter, problems have been ordered ḟrom the easiest
problem with the smallest calculations to the most di ḟ ḟicult problem with the largest
calculations. There ḟore, students are suggested to start studying the textbook ḟrom the
easiest problems and continue practicing until they reach the normal and then the hardest
ones. On the other hand, this classi ḟication can help instructors choose their desired problems
to conduct a quiz or a test. Moreover, the classi ḟication o ḟ computation amount can help
students manage their time during ḟuture exams and instructors give the appropriate problems
based on the exam duration.
Since the problems have very detailed solutions and some o ḟ them include multiple methods
o ḟ solutions, the textbook can be use ḟul ḟor the underprepared students. In addition, the
textbook is bene ḟicial ḟor knowledgeable students because it includes advanced exercises.
In the preparation o ḟ problem solutions, use o ḟ typical methods o ḟ 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 ḟirst method o ḟ problem solution. By considering
this key point, the textbook is in the direction o ḟ instructors’ lectures, and the instructors will not see
any untaught problem solutions in their students’answer sheets.
The Iranian University Entrance Exams ḟor the Master’s and PhD degrees o ḟ Electrical
Engineering major is the main re ḟerence o ḟ the textbook; however, all the problem solutions
have been provided by me. The Iranian University Entrance Exam is one o ḟ the most competi-
tive university entrance exams in the world that allows only 10% o ḟ the applicants to get into
prestigious and tuition- ḟree Iranian universities.
