分(fen)流(liu)器是生活中常見的(de)一種電(dian)(dian)(dian)阻(zu)器，通(tong)常把在電(dian)(dian)(dian)流(liu)上測(ce)量電(dian)(dian)(dian)壓(ya)，從(cong)而(er)間接(jie)測(ce)量電(dian)(dian)(dian)流(liu)的(de)元件叫做(zuo)分(fen)流(liu)器；分(fen)流(liu)器廣義定義：根據直流(liu)電(dian)(dian)(dian)流(liu)通(tong)過電(dian)(dian)(dian)阻(zu)時在電(dian)(dian)(dian)阻(zu)兩端產生電(dian)(dian)(dian)壓(ya)的(de)原理制成，與測(ce)量儀器的(de)電(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)路并聯，以擴大其(qi)測(ce)量范圍；分(fen)流(liu)器分(fen)為精密分(fen)流(liu)器和普(pu)通(tong)分(fen)流(liu)器
