簡介
分(fen)流(liu)(liu)器是(shi)生活中常(chang)見的一種電(dian)(dian)(dian)(dian)阻器，通常(chang)把在電(dian)(dian)(dian)(dian)流(liu)(liu)上測量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)壓，從而(er)間接測量(liang)(liang)(liang)電(dian)(dian)(dian)(dian)流(liu)(liu)的元件叫(jiao)做(zuo)分(fen)流(liu)(liu)器；分(fen)流(liu)(liu)器廣義(yi)定義(yi)：根據直流(liu)(liu)電(dian)(dian)(dian)(dian)流(liu)(liu)通過電(dian)(dian)(dian)(dian)阻時在電(dian)(dian)(dian)(dian)阻兩端產(chan)生電(dian)(dian)(dian)(dian)壓的原理制(zhi)成，與(yu)測量(liang)(liang)(liang)儀器的電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)路并聯，以擴大(da)其測量(liang)(liang)(liang)范圍；分(fen)流(liu)(liu)器分(fen)為精密分(fen)流(liu)(liu)器和普通分(fen)流(liu)(liu)器
