電(dian)(dian)阻(zu)(zu)有很多(duo)種(zhong)。根(gen)據電(dian)(dian)阻(zu)(zu)材料(liao)，可(ke)分為(wei)繞(rao)線型(xing)(xing)(xing)和非繞(rao)線型(xing)(xing)(xing)。非繞(rao)線型(xing)(xing)(xing)分為(wei)合(he)成型(xing)(xing)(xing)和薄膜(mo)(mo)(mo)型(xing)(xing)(xing)。薄膜(mo)(mo)(mo)型(xing)(xing)(xing)包括碳膜(mo)(mo)(mo)型(xing)(xing)(xing)、金屬膜(mo)(mo)(mo)型(xing)(xing)(xing)、金屬箔型(xing)(xing)(xing)、金屬氧化膜(mo)(mo)(mo)型(xing)(xing)(xing)、玻(bo)璃釉膜(mo)(mo)(mo)型(xing)(xing)(xing)等(deng)；根(gen)據電(dian)(dian)阻(zu)(zu)的特殊(shu)用途，可(ke)分為(wei)熱敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)、壓敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)、光敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)、力(li)敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)、磁敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)、氣敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)、濕敏(min)(min)(min)電(dian)(dian)阻(zu)(zu)，
滑動電(dian)阻和(he)熱敏電(dian)阻是汽(qi)車上常見的電(dian)阻。
汽車電(dian)(dian)(dian)阻(zu)的作用是(shi)限制電(dian)(dian)(dian)路(lu)內電(dian)(dian)(dian)流(liu)。在(zai)電(dian)(dian)(dian)子系(xi)統中(zhong)，電(dian)(dian)(dian)阻(zu)的作用非常重要。除作為元件的標(biao)準(zhun)電(dian)(dian)(dian)阻(zu)外，其(qi)他各部件都有(you)一個可影響電(dian)(dian)(dian)路(lu)電(dian)(dian)(dian)壓和電(dian)(dian)(dian)流(liu)的電(dian)(dian)(dian)阻(zu)值。 固定(ding)電(dian)(dian)(dian)阻(zu)器(qi)和可變(bian)電(dian)(dian)(dian)阻(zu)器(qi)在(zai)機動車電(dian)(dian)(dian)子系(xi)統內使(shi)用。
以下是對其的擴展介紹：、
1、電(dian)(dian)阻(zu)(zu)(zu)的(de)介(jie)紹：電(dian)(dian)阻(zu)(zu)(zu)是描述導(dao)體導(dao)電(dian)(dian)性能(neng)的(de)物理量，用R表示。電(dian)(dian)阻(zu)(zu)(zu)的(de)大小可以用來衡量導(dao)體對電(dian)(dian)流阻(zu)(zu)(zu)礙作用的(de)強弱，即導(dao)電(dian)(dian)性能(neng)的(de)好壞。電(dian)(dian)阻(zu)(zu)(zu)的(de)量值與導(dao)體的(de)材料、形狀、體積以及周(zhou)圍(wei)環境等因(yin)素有關。
2、電(dian)阻(zu)的分(fen)類：不同導體的電(dian)阻(zu)按其性質(zhi)的不同還(huan)可分(fen)為(wei)(wei)兩種類型。一類稱(cheng)為(wei)(wei)線性電(dian)阻(zu)或(huo)歐(ou)姆電(dian)阻(zu)，滿足歐(ou)姆定(ding)律; 另一類稱(cheng)為(wei)(wei)非線性電(dian)阻(zu)，不滿足歐(ou)姆定(ding)律。
