In 2009, the master's entrance examination "Fundamentals of Electrical Engineering" was reviewed, and the examination outline was the first part of the examination. I. Nature of the Examination The National Postgraduate Entrance Examination is set up for universities to recruit postgraduate students. The basic course of circuit is a main course (degree course) of the first-level discipline of electrical engineering in Southeast University. For undergraduate graduates in colleges and universities, the courses must reach a passing level or above in order to obtain a bachelor's degree. This course is listed as a required course for graduate students in this discipline, and 150 is included in the total score of postgraduate entrance examination. Ensure that the admitted students have solid professional basic knowledge and strong ability to analyze problems. Second, the scope of the examination. The examination scope of electrotechnics foundation includes: basic concepts and laws of circuits, equivalent transformation of circuits, general analysis methods of circuits, commonly used circuit theorems, circuit analysis with ideal operational amplifiers, transient analysis of circuits, concept of phasor, analysis of sinusoidal current circuits (including mutual inductance and three-phase circuits), analysis of non-sinusoidal periodic current circuits, and analysis of linear circuits with Laplace transform. See the second part of this outline for the main points of the exam.
