摘要
测定磁电式电表的内阻,是物理教学中的重要内容。如何选用合适的方法,正确测定磁电式电表的内阻,在具体操作过程中具有一定的难度。从磁电式表的基本原理出发,通过具体的分析研究得出了四种精确测定内阻的方法,并通过相关的实例进行了引证。
It is the important content in physical teaching to measure magnetic-electric ammeter＇s resistance. Some people have certain difficulties in measuring the magnetic-electric ammeter＇s resistance. Based on the fundamental of magnetic-electric ammeter and concrete analysis, the author shows us four kinds of accurate methodologies to measure resistance. And these methodologies are proved by examples.
