不同阻值范圍電阻測量方法的研究,摘要:電阻分為低、中、高電阻三種,低于1Ω的為低電阻,1-106Ω的為中電阻,大于106Ω的為高電阻。不同的電阻有不同的測量方法,如低電阻因為電阻較小,可用直流雙臂電橋測;而高電阻,因其電流比較小,可用沖擊電流計測量。中電阻有多種測量方法。關(guān)鍵字:低電阻 中電阻 高電阻 電橋 沖擊電流計 滑線變阻器abstract :...

摘要:
電阻分為低、中、高電阻三種,低于1Ω的為低電阻,1-106Ω的為中電阻,大于106Ω的為高電阻。不同的電阻有不同的測量方法,如低電阻因為電阻較小,可用直流雙臂電橋測;而高電阻,因其電流比較小,可用沖擊電流計測量。中電阻有多種測量方法。

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
