| 500 | _a This introductory textbook on basic electrical engineering provides a firm foundation to the basic concepts of electrical circuits and systems. The material in the book can be considered in three parts—electric circuits (dc and ac), field parts (magnetic and electric), and electrical machines. Beginning with the fundamental concepts of electricity and electrical elements, it provides a balanced coverage of dc and ac electric circuits and electrical machines. The principles of operation of transformers, dc machines, both generator and motor including three-phase induction motors, as well as synchronous ac machines, both generator and motor, are covered in great detail. The book includes a fair number of solved illustrative examples and exercises, carefully designed to give the reader sufficient help in assimilating concepts and applying them to practical situations. The contents of the book meet the curriculum requirements of the first year undergraduate engineering programme prescribed in India. Additional support for the book will be made available at ww.universitiespress.com/BEEbookinfo | ||
