電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)有很多種。根據電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)材(cai)料，可分為(wei)繞線(xian)型(xing)(xing)和非(fei)繞線(xian)型(xing)(xing)。非(fei)繞線(xian)型(xing)(xing)分為(wei)合(he)成型(xing)(xing)和薄(bo)膜(mo)型(xing)(xing)。薄(bo)膜(mo)型(xing)(xing)包括碳膜(mo)型(xing)(xing)、金(jin)(jin)屬膜(mo)型(xing)(xing)、金(jin)(jin)屬箔(bo)型(xing)(xing)、金(jin)(jin)屬氧化膜(mo)型(xing)(xing)、玻(bo)璃釉膜(mo)型(xing)(xing)等；根據電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的特(te)殊(shu)用途，可分為(wei)熱(re)敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、壓敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、光(guang)敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、力敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、磁敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、氣敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、濕敏(min)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)，
滑動電(dian)(dian)阻和(he)熱敏電(dian)(dian)阻是汽車(che)上(shang)常見的電(dian)(dian)阻。
汽車電(dian)(dian)(dian)(dian)阻的作(zuo)用是(shi)限制電(dian)(dian)(dian)(dian)路內電(dian)(dian)(dian)(dian)流。在電(dian)(dian)(dian)(dian)子(zi)系統中(zhong)，電(dian)(dian)(dian)(dian)阻的作(zuo)用非常重(zhong)要。除作(zuo)為元(yuan)件的標準電(dian)(dian)(dian)(dian)阻外，其他各(ge)部件都有一個可影響電(dian)(dian)(dian)(dian)路電(dian)(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)(dian)流的電(dian)(dian)(dian)(dian)阻值(zhi)。 固定電(dian)(dian)(dian)(dian)阻器和(he)可變電(dian)(dian)(dian)(dian)阻器在機動車電(dian)(dian)(dian)(dian)子(zi)系統內使用。
以下是對(dui)其(qi)的(de)擴展介(jie)紹(shao)：、
1、電(dian)阻(zu)的介紹：電(dian)阻(zu)是(shi)描(miao)述導(dao)體(ti)導(dao)電(dian)性(xing)能(neng)的物理(li)量，用R表示。電(dian)阻(zu)的大小可以(yi)用來衡量導(dao)體(ti)對電(dian)流阻(zu)礙作用的強(qiang)弱，即導(dao)電(dian)性(xing)能(neng)的好壞。電(dian)阻(zu)的量值與導(dao)體(ti)的材(cai)料(liao)、形狀(zhuang)、體(ti)積以(yi)及周圍環境等因素有關。
2、電(dian)(dian)阻(zu)的(de)分類(lei)：不(bu)同導體的(de)電(dian)(dian)阻(zu)按其性(xing)質的(de)不(bu)同還可分為(wei)兩種類(lei)型。一(yi)類(lei)稱(cheng)為(wei)線(xian)性(xing)電(dian)(dian)阻(zu)或歐姆電(dian)(dian)阻(zu)，滿足歐姆定(ding)律; 另一(yi)類(lei)稱(cheng)為(wei)非線(xian)性(xing)電(dian)(dian)阻(zu)，不(bu)滿足歐姆定(ding)律。
