✦ Synopsis

This book provides insights into practical aspects of electric circuits. The author provides real-world examples throughout this book. The devices chosen for this book can be found in nearly all laboratories. No expensive measurement devices are used throughout the book. Someone who reads this book has a better understanding of practical aspects of electric circuits. Chapter 1 introduces tools that will be used in the next chapters. Chapter 2 studies the resistors and contains 9 experiments. Chapter 3 studies the digital multimeters and contains 7 experiments. Chapter 4 studies Kirchhoff's voltage/current law, nodal/mesh analysis and Thevenin equivalent circuits. This chapter contains 5 experiments. Chapter 5 studies the first and second order circuits (RC, RL and RLC) and contains 4 experiments. Chapter 6 studies the DC and AC steady state behavior of electric circuits and frequency response of filters and has 5 experiments. Chapter 7 studies magnetic coupling and transformers and contains 3 experiments. Appendix A shows how different types of graphs can be drawn with MATLAB. Appendix B reviews the concept of root mean square.
