Introduction to Electric Circuits (EMT 114/3)

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. This book presents material in a clear and easy-to-understand manner. All important concepts, rules and formulas are highlighted after the explanation and are also summarised at the end of each chapter, making it easy to locate important facts and to study more effectively. The laboratory experiments at the end of each chapter are convenient for doing hands-on practice. These will motivate readers to master the circuit theory, especially college or university students or self-learners in this field.

Introduction to Circuit Analysis and Design takes the view that circuits have inputs and outputs, and that relations between inputs and outputs and the terminal characteristics of circuits at input and output ports are all-important in analysis and design. Two-port models, input resistance, output impedance, gain, loading effects, and frequency response are treated in more depth than is traditional. Due attention to these topics is essential preparation for design, provides useful preparation for subsequent courses in electronic devices and circuits, and eases the transition from circuits to systems.
