This book contains a number of selected problems in electric circuits. It includes exercises involving the application of ac analysis methods, frequency response, three phase circuits, power analysis, magnetically coupled circuits, Fourier series and Fourier transform, Laplace transform and two-ports networks. Emphasis has been given on understanding not only the theorems but also the basic techniques applied in the analysis of electric circuits. Thus, each problem is analytically solved by choosing the most appropriate technique. When students successfully complete the study of this book, they will have a good working knowledge of basic circuit principles and a demonstrated ability to solve a variety of circuit-related problems.
