电容器是电子线路中最为常见的元器件之一,由于其与生活联系密切,因此,关于其各特性的试题在高考中屡见不鲜。同时笔者在教学中也发现,电容器的相关概念具有较强的实验性和抽象性,这给学生的理解和内化带来了一定的困难,为此笔者对电容器的概念做了细致的分析,借助多用电表补充了几个小型的探究性实验,将学生最为熟悉的实验方法与抽象的电容概念联系到一起,丰富学生感性 Capacitors are one of the most common components in electronic circuits. Because of their close connection with life, the questions about their characteristics are not uncommon in college entrance examination. At the same time I also found in the teaching, the relevant concepts of capacitors with strong experimental and abstract, which gives students a certain degree of understanding and internalization, for which I made a careful analysis of the concept of capacitors, With the use of multi-meter supplemented several small inquiry experiments, the students are most familiar with experimental methods and abstract capacitance concept linked together to enrich the sensibility of students
