Basic Electrical and Electronics Engineering has been written primarily for the first year undergraduate students of engineering to help them understand the basic principles of electrical and electronics engineering. The first part of the book discusses the scope of electrical engineering and gives a detailed coverage on network theorems, magnetic circuits, transformer principles, alternating quantities, synchronous machines, induction motors, basic analogue instruments and power systems. The second part of the book deals with the concepts of electronics engineering and provides an in-depth understanding of semiconductors and diodes, transistors, oscillators and amplifiers. Additionally, the book explains the principles of transducers, telecommunication and information technology, digital systems and control systems in separate chapters.
