原則(ze)上(shang)說(shuo)，參(can)考(kao)點(dian)(dian)可(ke)以任意選定。在(zai)(zai)電(dian)(dian)(dian)工領(ling)域，通常(chang)選電(dian)(dian)(dian)路里的(de)接地點(dian)(dian)為參(can)考(kao)點(dian)(dian)，在(zai)(zai)電(dian)(dian)(dian)子電(dian)(dian)(dian)路里，常(chang)取機殼為參(can)考(kao)點(dian)(dian)。在(zai)(zai)實際應(ying)用時，僅知道兩點(dian)(dian)間的(de)電(dian)(dian)(dian)壓往(wang)往(wang)不夠，還(huan)要(yao)求知道這(zhe)兩點(dian)(dian)中(zhong)哪一(yi)點(dian)(dian)電(dian)(dian)(dian)位(wei)高(gao)(gao)，哪一(yi)點(dian)(dian)電(dian)(dian)(dian)位(wei)低(di)。例(li)如，對于(yu)半導體二(er)極管來說(shuo)，還(huan)有(you)其陽極電(dian)(dian)(dian)位(wei)高(gao)(gao)于(yu)陰極電(dian)(dian)(dian)位(wei)時才導通；對于(yu)直(zhi)流(liu)電(dian)(dian)(dian)動機來說(shuo)，老爺車租賃(lin)，繞(rao)組兩端的(de)電(dian)(dian)(dian)位(wei)高(gao)(gao)低(di)不同

廈門君朗益電(dian)動車有限公(gong)司以交通運輸為主，建立了完善的產(chan)品(pin)體系(xi)。主營：電(dian)動車，電(dian)動旅(lv)游(you)觀光車，老爺(ye)車翻(fan)新，電(dian)動巡(xun)邏(luo)車，電(dian)動環衛車，電(dian)動消防車，電(dian)瓶(ping)車租(zu)賃、保(bao)養維修(xiu)等(deng)。

電(dian)(dian)壓(ya)是推動(dong)自由電(dian)(dian)荷定向移動(dong)形成(cheng)電(dian)(dian)流(liu)的(de)(de)原因。電(dian)(dian)流(liu)之(zhi)所(suo)以能夠在(zai)導線中(zhong)(zhong)流(liu)動(dong)，也(ye)是因為在(zai)電(dian)(dian)流(liu)中(zhong)(zhong)有著高電(dian)(dian)勢(shi)和低電(dian)(dian)勢(shi)之(zhi)間(jian)的(de)(de)差(cha)別(bie)。這種差(cha)別(bie)叫電(dian)(dian)勢(shi)差(cha)，廈門老爺車，也(ye)叫電(dian)(dian)壓(ya)。換(huan)句話說(shuo)。在(zai)電(dian)(dian)路中(zhong)(zhong)，任意兩點(dian)(dian)之(zhi)間(jian)的(de)(de)電(dian)(dian)位差(cha)稱為這兩點(dian)(dian)的(de)(de)電(dian)(dian)壓(ya)。通(tong)常用字母(mu)U代表電(dian)(dian)壓(ya)。

減小來自電源的噪(zao)聲電源在(zai)向系統提供(gong)能源的同時，也將其噪(zao)聲加到所(suo)供(gong)電的電源上。電路中微控(kong)制(zhi)器的復位線(xian)(xian)，中斷線(xian)(xian)，以及其它一些控(kong)制(zhi)線(xian)(xian)受外界(jie)噪(zao)聲的干擾(rao)。電網上的強干擾(rao)通過電源進(jin)入(ru)電路。即使電池供(gong)電的系統，電池本(ben)身(shen)也有高頻噪(zao)聲。
