电学设计性实验一直以来都是高考的重点,伏安法测电阻是电学的一个基本实验,但随着课程改革不断向前推进,由此实验衍生出来的电学设计性实验种类繁多.试题常出现只有电压表或只有电流表或者虽然两种电表都提供,但电压表的满偏电流远大于电流表的满偏电流……,这些试题命题的本意还是考查学生利用伏安法测电阻的能力,这些试题有何特点,如何有效解决?笔者不妨借本文谈谈一点拙见,不足之处还请各位同行批评指正.
Electrical design experiments have always been the focus of college entrance examination, voltammetry resistance measurement is a basic electrical experiment, but as the curriculum reform continues to move forward, the experiment derived from a wide range of electrical design experiments. Only the voltmeter or only the ammeter or although both meters are provided, but the voltmeter full bias current is much larger than the ammeter full ampere current ... ... These questions are intended to test whether students use the volt-ampere resistance measurement ability of these questions What characteristics, how to effectively solve? I may wish to take this article to talk about my humble opinion, inadequacies also please colleagues to correct me.
