This textbook serves as a tutorial for engineering students. Fundamental circuit analysis methods are presented at a level accessible to students with minimal background in engineering. The emphasis of the book is on basic concepts, using mathematical equations only as needed. Analogies to everyday life are used throughout the book in order to make the material easier to understand. Even though this book focuses on the fundamentals, it reveals the authors' deep insight into the relationship between the phasor, Fourier transform, and Laplace transform, and explains to students why these transforms are employed in circuit analysis.
Solving circuit problems is less a matter of knowing what steps to follow than why those steps are necessary. And knowing the why stems from an in-depth understanding of the underlying concepts and theoretical basis of electric circuits. Setting the benchmark for a modern approach to this fundamental topic, Nassir Sabah’s Electric Circuits and Signals supplies a comprehensive, intuitive, conceptual, and hands-on introduction with an emphasis on creative problem solving. A Professional Education Ideal for electrical engineering majors as a first step, this phenomenal textbook also builds a core knowledge in the basic theory, concepts, and techniques of circuit analysis, behavior, and operation for students following tracks in such areas as computer engineering, communications engineering, electronics, mechatronics, electric power, and control systems. The author uses hundreds of case studies, examples, exercises, and homework problems to build a strong understanding of how to apply theory to problems in a variety of both familiar and unfamiliar contexts. Your students will be able to approach any problem with total confidence. Coverage ranges from the basics of dc and ac circuits to transients, energy storage elements, natural responses and convolution, two-port circuits, Laplace and Fourier transforms, signal processing, and operational amplifiers. Modern Tools for Tomorrow’s Innovators Along with a conceptual approach to the material, this truly modern text uses PSpice simulations with schematic Capture® as well as MATLAB® commands to give students hands-on experience with the tools they will use after graduation. Classroom Extras When you adopt Electric Circuits and Signals, you will receive a complete solutions manual along with its companion CD-ROM supplying additional material. The CD contains a WordTM file for each chapter providing bulleted, condensed text and figures that can be used as class slides or lecture notes.
Appropriate for introductory college courses in electrical engineering for major and nonmajors alike. Assumes that students have already completed one year of college-level calculus and physics. This text presents the basics of electrical engineering from the perspective of the primary principles behind the subject, rather than dwelling on superficial details. It is based on three objectives: to explain the fundamental ideas behind electrical engineering, to emphasize the unity of the subject, and to bring an understanding of the subject within the reach of all engineers.
Circuit theory is a core course in every Electrical Engineering curriculum, with a wide range of applications to a variety of problems related to electrical systems and subsystems, such as power transmission systems, communication systems, control systems and electronics systems in general.This book includes a complete and self contained presentation of fundamental concepts, definitions, principles and techniques on Electric Circuits, and has been designed to be an excellent supplementary textbook and help all Electrical Engineering and Technology students to understand in depth, the essentials of the theory involved and develop the insight and the analytical skills needed, in order to pursue studies in more complicated topics in circuits and electrical systems in general.Topics covered include, Electric Power and Energy, The Basic Elements in Electric Circuits and their respective Ohm's Law, The Electric Energy Sources and their Mathematical Models, for both Independent and Controlled Sources, The Kirchhoff's Laws and applications, Equivalent Circuits, Capacitors and Inductors, Transients in simple R-L or R-C circuits.The content of this book is divided in 10 chapters.The content of each chapter is shown in the Table of Contents. At the end of the book, we include an Appendix, showing how to solve a first order Differential Equation, Linear with Constant Coefficients. This will help the students to understand the operation of circuits containing ohmic resistors and capacitors or ohmic resistors and inductors. The study of such circuits in general, is described by first order differential equations.The 65 illustrative solved Examples and the 155 characteristic Problems to be solved are design to help students develop a solid theoretical background, broaden their knowledge and sharpen their analytical skills on the subject. A brief Hint or detailed outline of the procedure to follow, in solving complicated problems is often given.Finally answers to odd numbered problems are also given, so that the students can verify the validity of their own solution.
Relevant applications to electronics, telecommunications and power systems are included in a comprehensive introduction to the theory of electronic circuits for physical science students.
An Introduction to Electric Circuits is essential reading for first year students of electronics and electrical engineering who need to get to grips quickly with the basic theory. This text is a comprehensive introduction to the topic and, assuming virtually no knowledge, it keeps the mathematical content to a minimum.As with other textbooks in the series, the format of this book enables the student to work at their own pace. It includes numerous worked examples throughout the text and graded exercises, with answers, at the end of each section.
This book provides an understandable and effective introduction to the fundamentals of DC/AC circuits. It covers current, voltage, power, resistors, capacitors, inductors, impedance, admittance, dependent/independent sources, the basic circuit laws/rules (Ohm's law, KVL/KCL, voltage/current divider rules), series/parallel and wye/delta circuits, methods of DC/AC analysis (branch current and mesh/mode analysis), the network theorems (superstition, Thevenin's/Norton's theorems, maximum power transfer, Millman's and substitution theorems), transient analysis, RLC circuits and resonance, mutual inductance, transformers, and more. The English version of this book continues in the spirit of its successful Chinese version, which was published by Higher Education Press (the largest and most prominent publisher of educational books in China) in 2005 and reprinted in 2009. Ideal for University students or professionals wishing to gain a good understanding of electrical circuits.
The book, now in its Second Edition, presents the concepts of electrical circuits with easy-to-understand approach based on classroom experience of the authors. It deals with the fundamentals of electric circuits, their components and the mathematical tools used to represent and analyze electrical circuits. This text guides students to analyze and build simple electric circuits. The presentation is very simple to facilitate self-study to the students. A better way to understand the various aspects of electrical circuits is to solve many problems. Keeping this in mind, a large number of solved and unsolved problems have been included. The chapters are arranged logically in a proper sequence so that successive topics build upon earlier topics. Each chapter is supported with necessary illustrations. It serves as a textbook for undergraduate engineering students of multiple disciplines for a course on ‘circuit theory’ or ‘electrical circuit analysis’ offered by major technical universities across the country. SALIENT FEATURES • Difficult topics such as transients, network theorems, two-port networks are presented in a simple manner with numerous examples. • Short questions with answers are provided at the end of every chapter to help the students to understand the basic laws and theorems. • Annotations are given at appropriate places to ensure that the students get the gist of the subject matter clearly. NEW TO THE SECOND EDITION • Incorporates several new solved examples for better understanding of the subject • Includes objective type questions with answers at the end of the chapters • Provides an appendix on ‘Laplace Transforms’
When revising this standard text in electric circuits, the author retained the features that have kept the book a success and expanded coverages of ICs, printed wiring boards, equivalent circuit analysis, and superconductivity. Topics are developed in a methodical, step-by- step, cause-and-effect manner.
