This book on network analysis is generally one of the basic texts a student of engineering refers to. While currently available books on the subject adequately cover the different facets the authors feel that there is still a need for a book which provides all the necessary material required by the students of electrical and electronic engineering at one place for a solid foundation in the area of Circuit Theory. The purpose of writing this book is therefore to fulfil this requirement. The material presented in this book can be covered adequately in two semesters. The authors have tried to present the concepts of network analysis in a lucid way so that a student reading this book will be able to understand the subject easily. No prerequisites other than a rudimentary knowledge of physics including the concepts of electricity and magnetism are necessary.
