纵观历年高考,电学实验一直是高考的热点,而得分率却很低．用“用伏特表和安培表测定电流的电动势和内电阻”实验,在电学实验中,在整个高中物理实验中占的地位都是举足轻重的,该实验的系统误差的分析,以不同的题型常见于高中物理的试卷中,尤让学生棘手．本文就图象法及等效电源法加以讨论．
Throughout the college entrance examinations, electrical experiments have always been a hot spot for the college entrance examination, but the scoring rate is very low. The experiment of measuring the electromotive force and internal resistance of a current using a voltmeter and an amperometric meter is an important part of the electrical experiment in the entire high school physics experiment. The system error of the experiment is analyzed with different questions. Commonly used in high school physics test papers, it is especially tricky for students. This article discusses the image method and equivalent power method.
