A Text Book On Basic Electrical & Electronics Engineering

This book is designed to meet the academic requirements of the Basic Electrical and Electronics Engineering course, which is common to all engineering branches. It provides a balanced introduction to fundamental electrical principles and essential electronics concepts. The content begins with DC and AC circuit analysis, helping students understand electrical quantities, circuit laws, and key theorems. It then covers major electrical machines such as DC motors, generators, transformers, induction motors, and alternators, explaining their construction, operation, and applications. Measuring instruments including PMMC and MI devices, along with the Wheatstone bridge, are discussed to build a foundation in electrical measurements. The book also highlights energy resources, power generation systems, and practical aspects of electricity usage such as billing, tariffs, and safety measures, linking theory to real-world applications. The electronics section introduces semiconductor devices like diodes, Zener diodes, and transistors, followed by basic circuits including rectifiers, power supplies, amplifiers, and instrumentation systems. The final unit covers digital electronics, focusing on number systems, logic gates, Boolean algebra, and basic combinational and sequential circuits. Concepts are presented clearly, supported by diagrams, simple numerical examples, and practical insights. The aim is to help students understand and apply core electrical and electronics engineering principles, preparing them for advanced studies and fostering curiosity and innovation.
