2000年高考全国物理卷第16题是一个得分率很低的题。这个题难在哪里?给人什么启发呢?先看该题的原文: 从表1中选出适当的实验器材,设计一电路来测量电流表A_1的内阻r_1,要求方法简捷,有尽可能高的测量精度,并能测得多组数据。 The 16th issue of the national physical examination paper in the 2000 college entrance exam was a question with a very low score. This question is difficult where? What inspired people? First look at the original of the question: Select the appropriate laboratory equipment from Table 1, design a circuit to measure the internal resistance of the current meter A_1 r_1, requiring a simple method, as high as possible The accuracy of the measurement, and can measure many sets of data.
