人教版《高中物理选修3-1》中有三个重要的电学实验:探究决定导体电阻的因素、描绘小灯泡的伏安特性曲线、测定电源的电动势和内阻,这三个实验所涉及的实验原理也是高考实验题的基础.这三个实验都涉及了U-I图象,归纳分析每个U-I图象的特点有助于进一步理解和掌握这三个实验,进而运用
There are three important electrical experiments in the PEP: High School Physics Elective 3-1: explore the factors that determine the conductor resistance, describe the volt-ampere characteristic curve of the small bulb, and measure the electromotive force and internal resistance of the power supply. The three experiments involved The experimental principle is also the basis for the entrance exam questions.These three experiments are related to the UI images, inductive analysis of the characteristics of each UI image helps to further understand and master these three experiments, and then use
