電阻率
電阻率
電阻率,又稱電阻係數,是描述材料導電性能的物理量。 電阻率在數值上等於單位長度、單位截面的某種物質的電阻,數值上等於長度為一公尺,橫截面為一平方公尺的該種物質的電阻大小。 電阻率的倒數為電導率。電阻率與導體的長度、橫截面積等因素無關,是導體材料本身的電學性質,由導體的材料決定,且與溫度有關。 電阻率在國際單位制的單位是Ω·m,讀作歐姆公尺,簡稱歐公尺。常用單位為「歐姆·公尺」。 電阻率較低的物質稱…
維基百科維基百科精密的電阻温度計是用鉑做的。 已知鉑絲的電阻與温度的對應關係,只需測出鉑絲的電阻就可以知道環境温度。 有些合金如錳銅和康銅合金,電阻率幾乎不受温度變化的影響,常用來製作標準電阻 [8] [9] 。
baike.baidu.hk各種材料的電阻率都隨温度的變化而變化。 純金屬的電阻率隨温度的升高而增大,電阻温度計就是利用金屬的這種特性製成的,它可以用來測量很高的温度。
4. 超導體 的直流電阻率在一定的低溫下突然消失,被稱作零電阻效應。 導體 沒有了電阻。
factpedia.org電阻率是反映物質對 電流 阻礙作用的屬性,電阻是反映物體對電流阻礙作用的能力大小。
1.電阻率 ρ 不僅和導體的材料有關,還和導體的温度有關。 在温度變化不大的範圍內,幾乎所有金屬的電阻率隨温度作線性變化,即 ρ = ρo (1+ at )。
baike.baidu.hk國際單位制 中,電阻率的單位是歐姆·米,常用單位是歐姆·平方毫米/米。 與 導體 長度 L ,橫截面積 S 無關,只與物體的材料和温度有關,有些材料的電阻率隨着温度的升高而增大,有些反之。
