電表分為(wei)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)、電(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)和電(dian)(dian)(dian)(dian)(dian)能表(biao)，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)是測(ce)量電(dian)(dian)(dian)(dian)(dian)路中(zhong)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大小(xiao)的(de)工具，而(er)電(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)是用來測(ce)量電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)，電(dian)(dian)(dian)(dian)(dian)能表(biao)是用來測(ce)量電(dian)(dian)(dian)(dian)(dian)能的(de)儀表(biao)，又稱電(dian)(dian)(dian)(dian)(dian)度表(biao)，火表(biao)，千瓦小(xiao)時(shi)表(biao)，指測(ce)量各種電(dian)(dian)(dian)(dian)(dian)學量的(de)儀表(biao)，俗稱電(dian)(dian)(dian)(dian)(dian)度表(biao)、火表(biao)。

電壓表和電流表的相同點與區別

電壓表和電流表的相同點：

1、 電流都(dou)要從“+”接線(xian)柱流進，從“-”接線(xian)柱流出(chu) ；

2、 被測(ce)電流或(huo)電壓都(dou)不能超過(guo)所(suo)選量(liang)程或(huo)接線柱旁標出的測(ce)量(liang)值；

3、在預先(xian)不知道被測電流或電壓的大約值時，需(xu)先(xian)用(yong)大量程(cheng)試觸。

電流表與電壓表的區別：

1、電(dian)流表(biao)測電(dian)流，串聯在(zai)所測電(dian)流支(zhi)路上；電(dian)壓表(biao)測電(dian)壓，并聯在(zai)所測原(yuan)件上；

2、電流表不可以直接(jie)接(jie)在電源兩側(ce)，會短路燒壞(huai)電源；但是(shi)電壓表可以直接(jie)接(jie)在電源兩側(ce)，測得的是(shi)電源電動勢。

3、電流(liu)表(biao)要與電路(lu)(lu)串(chuan)聯，電壓表(biao)要與電路(lu)(lu)并(bing)聯。
