This book introduces readers to the basic concepts and tools associated with the fields of electrical engineering technology, including electronics, apparatus and machines and advanced networks and systems studies. It treats the subject relying primarily on algebra and trigonometry. Stressing analytical reasoning by applying the concepts learned to general solved examples at the end of each chapter, it follows the IEEE recommended standards and the International Systems of Units (SI) for all symbols, diagrams and units. It also emphasizes the why and how before getting involved in algebraic manipulations and the fundamental understanding of OHM's law KVL and KCL.
