教学用滑(hua)线变阻(zu)器实验室常(chang)用滑(hua)线变阻(zu)器来改变电(dian)(dian)路(lu)(lu)中(zhong)的电(dian)(dian)流或电(dian)(dian)压，分(fen)别连(lian)接成(cheng)制(zhi)流电(dian)(dian)路(lu)(lu)和分(fen)压电(dian)(dian)路(lu)(lu)，使(shi)用时应注意，接通电(dian)(dian)源前，制(zhi)流电(dian)(dian)路(lu)(lu)中(zhong)滑(hua)动(dong)端(duan)T应置(zhi)(zhi)于(yu)电(dian)(dian)阻(zu)Z大位(wei)置(zhi)(zhi)（N端(duan)）；分(fen)压电(dian)(dian)路(lu)(lu)中(zhong)，滑(hua)动(dong)端(duan)T应置(zhi)(zhi)于(yu)电(dian)(dian)阻(zu)Z小(xiao)位(wei)置(zhi)(zhi)（N端(duan)）。

教学用滑线(xian)变(bian)阻(zu)器实(shi)验室常用滑线(xian)变(bian)阻(zu)器来改变(bian)电(dian)路中的电(dian)流或电(dian)压，分(fen)别(bie)连接成制(zhi)流电(dian)路和分(fen)压电(dian)路，使用时应注意，接通电(dian)源前，制(zhi)流电(dian)路中滑动(dong)(dong)端(duan)(duan)T应置于(yu)电(dian)阻(zu)Z大位置（N端(duan)(duan)）；分(fen)压电(dian)路中，滑动(dong)(dong)端(duan)(duan)T应置于(yu)电(dian)阻(zu)Z小位置（N端(duan)(duan)）。

教学(xue)用(yong)滑(hua)线变阻器实验(yan)室常用(yong)滑(hua)线变阻器来(lai)改变电(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)的电(dian)(dian)(dian)流或电(dian)(dian)(dian)压(ya)，分(fen)别连(lian)接(jie)成制流电(dian)(dian)(dian)路(lu)(lu)(lu)和(he)分(fen)压(ya)电(dian)(dian)(dian)路(lu)(lu)(lu)，使用(yong)时应注意，接(jie)通电(dian)(dian)(dian)源前，制流电(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)滑(hua)动端(duan)(duan)T应置(zhi)于电(dian)(dian)(dian)阻Z大(da)位(wei)置(zhi)（N端(duan)(duan)）；分(fen)压(ya)电(dian)(dian)(dian)路(lu)(lu)(lu)中(zhong)，滑(hua)动端(duan)(duan)T应置(zhi)于电(dian)(dian)(dian)阻Z小位(wei)置(zhi)（N端(duan)(duan)）。
