Fundamentals of Electrical Engineering is a text targeted towards first-year undergraduate students across all streams of Engineering. This book aims at explaining the basic concepts of electrical circuits in a clear-cut and simplified manner. It begins from the topics which students have already dealt with at the 10+2 level and relates them to the syllabus of a first-year college-level course, thus ensuring a smooth progressive transition from Physics to Electrical Engineering. This book explains methods of solving electrical circuits that are based on first principles but are also described in a stepwise manner.
