A study of the basic Electronic Components is vital for any course in Electrical, Electronics and Communication. This book covers the various types of components used in all our circuits involving any analog or digital electronics. The knowledge of components enables one to design circuits and make PCBs, efficiently and economically. Wide coverage of all passive and active components, electro-mechanical parts is given in the book. Design rules and formulae are provided wherever necessary. The book will be useful to all those involved in Electronic Industries, assembling, testing and servicing circuits and boards of various kinds and purposes. About The Author: K.
