摘要
灵敏电流计内阻及电流常数的测量方法有多种,从电路类型分为分压测量法和限流测量法。本文对两种方法进行分析比较,得出使用分压测量法精确度较高,并给出分压测量法的简单计算。
There are many methods to measure internal resistance and current constant for sensitive galvanometer.According to the circuit types,we classify it into divided voltage measurement and current limiting measurement.In this paper,we analyze and compare the two measurements,and draw a conclusion that the accuracy of divided voltage measurement is higher.In addition,the simple calculation of divided voltage measurement is given out.
