溫度對電阻的影響

產品應用 溫度對電阻的影響

RS  電阻的產生 
 金屬由一群依一定規則排列原子構成，每顆原子均有一層 (或多層) 由電子組成的外売。這些在外売的電子能脫離原子核 
 的吸引力而到處流動，是金屬能導電的主要原因。當金屬兩端產生電勢差 (即電壓) 時，電子因電場的影晌而作規則的流 
 來源。動，是為電流。在現實中，物質的原子排列不可能為完全規則，因此電子在流動途中會被不按規則排列的原子打散，
 是為電阻的  高溫加速電子運動，增加電子被打散的機會，故熱的物體電阻較高。 
 橫切面面積大的金屬有較多空間予電子流動，故電阻較小。 
 電子橫過較長的金屬時一般會發生較多的碰撞，故長的金屬電阻較大。

Application  當溫度升高，為什麼半導體的電阻會下降﹖
