Product Description:
This text is an introduction to the basic principles of electrical engineering and covers DC and AC circuit analysis and Transients. It is intended for all engineering majors and presumes knowledge of first year differential and integral calculus and physics. The last two chapters include step-by-step procedures for the solutions of simple differential equations used in the derivation of the natural and forces responses. Appendices A, B, and C are introductions to MATLAB®, Simulink®, and SimPowerSystems® respectively. Appendix D is a review of Complex Numbers, and Appendix E is an introduction to matrices and determinants.
Preface
This text is an introduction to the basic principles of electrical engineering. It is the outgrowth of
lecture notes prepared by this author while employed by the electrical engineering and computer
engineering departments as adjunct instructor at various colleges and universities. Many of the
examples and problems are based on the author’s industrial experience. The text is an expansion
of our previous publication, Circuit Analysis I with MATLAB® Applications, ISBN 9780
970951120, and this text, in addition to MATLAB scripts for problem solution, includes
several Simulink® and SimPowerSystems® models. The pages where these models appear are
indicated n the Table of Contents.
The book is intended for students of college grade, both community colleges and universities. It
presumes knowledge of first year differential and integral calculus and physics. While some
knowledge of differential equations would be helpful, it is not absolutely necessary. Chapters 9 and
10 include stepbystep procedures for the solutions of simple differential equations used in the
derivation of the natural and forces responses. Appendices D and E provide a thorough review of
complex numbers and matrices respectively.
In addition to several problems provided at the end of each chapter, this text includes multiplechoice
questions to test and enhance the reader’s knowledge of this subject. Moreover, the
answers to these questions and detailed solutions of all problems are provided at the end of each
chapter. The rationale is to encourage the reader to solve all problems and check his effort for
correct solutions and appropriate steps in obtaining the correct solution. And since this text was
written to serve as a selfstudy, primary, or supplementary textbook, it provides the reader with a
resource to test the reader’s knowledge.
