“电阻的测量”是整个高中电学实验的核心,它不仅考查了学生独立完成实验的能力和实验设计能力,而且有效地考查了学生的电学基础知识。“电阻测量”方法非常多,变数非常大,但其根本之法还是伏安法,欧姆定律的应用也始终贯穿其中。对该实验进行探究,并与其他学生方法进行比较,可以得到测量多个未知电阻不宜用并联法的结论,从而培养实验创新能力和思维的灵活性。 The Measurement of Resistance is at the heart of the entire high school electrical experiment. It examines not only students’ ability to experiment independently but also experimental design capabilities, as well as effectively examining the student’s electrical fundamentals. “Resistance measurement ” method is very large, the variables are very large, but its fundamental method is volt-ampere law, the application of Ohm’s law also always runs through them. The experiment to explore, and compared with other student methods, you can get a number of unknown resistance measurement parallel method should not be the conclusion, so as to cultivate experimental innovation and thinking flexibility.
