This course talks about the fundamentals and analysis of electric circuits which are paths for transmitting electric currents. This course is one of the important courses for electrical engineering (EE) undergraduates. It presents fundamentals, basic laws, and theorems and analysis methods of electric circuits. The contents of this course provide a theoretical foundation for students who want to presume other electronic and electrical engineering courses, such as electronics, electrical machines, and communications.

The goal of this course is to build an understanding of concepts and ideas explicitly in terms of previous learning, to emphasize the relationship between conceptual understanding and problem–solving approaches, and to provide students with a strong foundation of engineering practices.

This course includes five parts. The first part is about DC circuits, covering the basic concepts, fundamental laws, and methods of circuit analysis techniques. The second part is the dynamics of first- and second-order circuits. The third part is about AC circuits, covering analysis of phasors, sinusoidal steady-state circuit, three-phase systems. The fourth part is the frequency-domain analysis, including frequency-selective circuits, Laplace transform, and Fourier Series. The last part is about the two-port circuits. 

The feature of this course is to combine both Chinese and English ways of describing electric variables and adopting circuit analysis techniques. It can help students understand the habits of electric engineers from different places.

To learn the fundamentals of Electric Circuits and can use these basics to solve practical problems in electrical and ectronics fields.

To understand the contents of this course, the student must have basic knowledge of Calculus, Algebra, and Physics.
