Hello B.Tech first year student,
Basic Electrical Engineering is a fundamental subject that forms the foundation of electrical engineering. It is typically a first-year course in a BTech program and covers the fundamental concepts of electrical circuits and devices, including DC and AC circuits, transformers, motors, generators, and basic electronics. The course aims to equip students with the knowledge and skills necessary to analyze and design electrical circuits and systems, as well as to introduce them to the practical applications of electrical engineering. The subject is essential for students pursuing a career in electrical engineering, as it provides a solid understanding of the underlying principles that govern the behavior of electrical systems.
I am sharing Basic Electrical Engineering question bank with answers and solutions in Q&A format for engineering/BTech first year. This is available as a PDF file for free download below.
