Circuit Theory is one of the oldest yet most important subjects for all Electrical and Electronics Engineers. It takes intuitive and fundamentals approach to understanding Electrical Circuits and their response to various signals. In our opinion, this subject is best understood by studying a variety of circuits and analyzing their behaviors. This book takes a practical approach to understanding this very important subject. Some of the highlighting features of the book are 200+ solved problems Clearly illustrated steps Extensive diagrams Quick reference of important formulae Primer of important calculus concepts Easy to understand Useful to all EE, EEE, ET&C Fundamentals Useful for Gate, IES and other competitive exams 3 Fully solved University papersAbout the AuthorAsang holds a BE in Electronics Engineering from VRCE, Nagpur and ME in Computer Science from IISc, Bangalore.
