The main content of this course contains linear and nonlinear resistive circuits, time domain analysis of the dynamic circuits, and the steady state analysis of the dynamic circuits with sinusoidal excitations. Important concepts, e.g. filters, resonance, quiescent point, etc., cutting-edge elements, e.g. MOSFETs and Op Amps, etc., systematic analyzing tools, e.g. node method and phasor method, etc., and real-world engineering applications, e.g. square wave generator and pulse power supply for railgun, etc., will be discussed in depth.

In order to facilitate the learning for students with middle school level, we prepare the necessary knowledge for calculus and linear algebra in week 0. With your effort, we can show you the fantastic view of electricity.

The circuit principle course is the most important basic course for all electrical majors. Subsequent basic courses and professional courses for all majors are based on the knowledge system of this course. Therefore, it is one of the "housekeeping courses" for undergraduates in electrical majors. The main contents of the circuit principle course include: linear resistance circuit analysis, non-linear resistance circuit analysis, time domain analysis of dynamic circuits and steady-state analysis of dynamic circuits under sinusoidal excitation. The teaching of the Circuit Principles course at Tsinghua University includes basic methods of circuit analysis, contemporary circuit components, practical engineering applications of circuit principles, etc., providing students with a solid foundation and rich applications.

In order to facilitate the learning of students with only middle school knowledge, the Circuit Principles MOOC specifically uses week 0 to prepare the necessary foundations of calculus, linear algebra and college physics and electricity. We are confident that you can understand the wonders of the electrical world.
