测量电阻的几种方法

Some Methods of Meassuring Resistance

电路中的许多元件,在使用时都要了解它的电阻值及其它特性。想要得知某导体的电阻率,一般也是先测电阻值。因此测量电阻在现代技术方面就显得较为重要。文章讨论了中值电阻的几种测量方法,和用双桥电路测低电阻的原理,以及电池内阻的测法。

We should know the characteristics of some circuit elements. In order to get the specific resistance we should measure the resistance first. Therefore, it is very important in modern technology. This article will discuss some methods of measuring resistance, principles and methods of measuring low resistance and internal resistance.
