一、高考对电学实验的考查分析与预测 :从近四年的考题情况来看 ,电学主要考查两个方面 ,一是伏安法 (或安阻法 ,伏阻法 )测电池电动势和内阻 (或电压表、电流表的电阻 ) ;二是电磁感应现象研究 .结合当前新教材、新大纲的改革精神 ,预计今后电学实验将会出现如下趋势 :仍是两
First, the college entrance examination on the electrical experiment analysis and prediction: From the past four years of the examination point of view, the main electrical examination of two aspects, one is the voltammetry (or resistance method, volt resistance method) measured battery electromotive force and internal resistance (or the resistance of voltmeters and ammeters); the second is the research of electromagnetic induction phenomena. In light of the spirit of the reform of the current new textbooks and new syllabuses, it is expected that the following trends will emerge in electrical experiments:
