This third edition of Basic Electrical Engineering provides a comprehensive coverage of the principles of electrical engineering for both electrical as well as non-electrical undergraduate students of engineering. Bsides an exhaustive coverage of topics such as network theory and analysis, magnetic circuits and energy conversion, ac and dc machines, basic analogue instruments, and power systems, the book also covers new topics based on review feedback including Millman's Theorem and Compensation Theorem for DC excitation. The book provides a chapter overview and recapitulation of important formulae in every chapter. It enables quick understanding of concepts through a wealth of well-illustrated figures and solved examples. It also supports numerous chapter-end exercises and multiple choice questions.
