电学实验可综合考查学生对欧姆定律、电表原理及使用等知识掌握,考查动态电路分析、电路故障分析、电路设计等能力。每年全国卷或地方卷对实验的考查中,电学实验必不可少,因而它是高考的重点;又因它对学生综合能力要求较高,难教难学,失分率也较高,因而它又是教学的难点。电路的设计、仪表及器材的选择又是难点中的难点。 Electrical experiments can be comprehensive examination of students Ohm’s law, the meter principle and use of knowledge to master, examine the dynamic circuit analysis, circuit failure analysis, circuit design and other capabilities. Every year, the national volume or local volume examination of the experiment, the electrical experiment is essential, so it is the focus of the college entrance examination; but also because of its high comprehensive ability of students, difficult to learn difficult, the loss rate is also high, so it It is also a difficult teaching. Circuit design, instrumentation and equipment selection is difficult in the difficult.
