This book is compiled based on the requirements of higher vocational colleges for cultivating applied high-skilled talents and the learning characteristics of higher vocational college students. This book consists of seven chapters, including basic concepts and laws of circuits, analysis of resistive circuits, single-phase sinusoidal AC circuits, three-phase sinusoidal AC circuits, non-sinusoidal periodic current circuits, transition processes of dynamic circuits, magnetic circuits and core coils. This book can be used by teachers and students majoring in electricity (strong and weak current) in higher vocational colleges and universities, and can also be used as a reference for engineering technicians and self-learners.
