There are four courses in the postgraduate entrance examination for electrical specialty: mathematics, English, politics and professional courses. Among them, mathematics, English and politics are the national unified examinations. I suggest looking for last year's outline to see what it is.
1, Mathematics: It is a preliminary test of mathematics and consists of calculus, linear algebra, probability theory and mathematical statistics. Refer to the outline of previous years for specific contents, and recommend the teaching material Calculus (up and down), Tongji Edition; Tongji Edition Linear Algebra, Zhejiang University Edition Probability Theory and Mathematical Statistics. Just buy the latest edition.
2, English: basically no scope, the main content is reading and writing, no listening. Still rely on the usual accumulation and some real question answering skills, you need to start early and the water will flow forever; You can buy some targeted training materials specifically for the postgraduate entrance examination.
3. Politics: It's basically a nonsense subject, but it can't be too bad. Including Ideological Cultivation and Legal Basis, Modern History of China, Basic Principles of Marxism and Socialism with Chinese characteristics. The textbooks are national textbooks, but it is not recommended to buy them. If it is a special postgraduate entrance examination, just buy Outline Analysis and match it with some targeted postgraduate entrance examination materials.
4. Specialized courses: most schools take the circuit test, and some, such as power system analysis in the preliminary examination of North China Electric Power University. The recommended circuit textbook is Qiu Guanyuan Circuit. But in any case, there are still many professional courses to take after the initial test, so the professional content still depends on it. The basic books I read include counting electricity, analog electricity, power system analysis, power system relay protection, electrical engineering, power electronics and automatic control theory. If you haven't learned to teach yourself, it's really difficult in a short time, so I suggest you don't make up your mind to take the postgraduate entrance examination easily, which may not be worth it. Please be careful.
