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 Masters 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 competitive university entrance exams in the world that allows only 10% of the applicants to get into prestigious and tuition-free Iranian universities.
