不同阻值范围电阻测量方法的研究,摘要:电阻分为低、中、高电阻三种，低于1Ω的为低电阻，1-106Ω的为中电阻，大于106Ω的为高电阻。不同的电阻有不同的测量方法，如低电阻因为电阻较小，可用直流双臂电桥测；而高电阻，因其电流比较小，可用冲击电流计测量。中电阻有多种测量方法。关键字：低电阻 中电阻 高电阻 电桥 冲击电流计 滑线变阻器abstract :...

摘要:
电阻分为低、中、高电阻三种，低于1Ω的为低电阻，1-106Ω的为中电阻，大于106Ω的为高电阻。不同的电阻有不同的测量方法，如低电阻因为电阻较小，可用直流双臂电桥测；而高电阻，因其电流比较小，可用冲击电流计测量。中电阻有多种测量方法。

Abstract :
Resistance can be divide into three kinds: the lower ,the middle and the higher. lower than 1Ω the lower resistance, between 1 to 106Ω the middle, higher than 106Ω the higher resistance. Each kind has different measurement method, for example, the lower resistance can be examined by the electric bridge of both arms of direct current because its relatively little resistance; And high resistance can be examined by Electric bridge Assault。 There are many kinds of measurement methods in middle resistance.
Key words:
Low resistance Middle resistance High resistance Electric bridge Assault the galvanometer Slippery line rheostat
