這是(shi)(shi)(shi)(shi)因為(wei)當對相(xiang)同長度(電(dian)(dian)(dian)阻)的(de)(de)電(dian)(dian)(dian)線通電(dian)(dian)(dian)相(xiang)同時間時，會(hui)產(chan)生與電(dian)(dian)(dian)流(liu)平(ping)方成正比(bi)的(de)(de)熱(re)量。由于熱(re)量是(shi)(shi)(shi)(shi)逸出的(de)(de)能(neng)量，因此(ci)是(shi)(shi)(shi)(shi)功(gong)率損耗。比(bi)如(ru)(ru)你(ni)需(xu)(xu)要3000W(瓦)的(de)(de)功(gong)率，如(ru)(ru)果電(dian)(dian)(dian)壓是(shi)(shi)(shi)(shi)100V，你(ni)就需(xu)(xu)要30A(安培)的(de)(de)電(dian)(dian)(dian)流(liu)，但是(shi)(shi)(shi)(shi)如(ru)(ru)果電(dian)(dian)(dian)壓是(shi)(shi)(shi)(shi)1000V，你(ni)只需(xu)(xu)要3A的(de)(de)電(dian)(dian)(dian)流(liu)。換句話(hua)說，如(ru)(ru)果電(dian)(dian)(dian)壓增(zeng)加10倍，電(dian)(dian)(dian)流(liu)量將減(jian)少到1/10，由此(ci)產(chan)生的(de)(de)功(gong)率損耗可以(yi)減(jian)少到1/100，或(huo)1/10的(de)(de)平(ping)方。出于這個原因，非常高的(de)(de)電(dian)(dian)(dian)壓用(yong)于長距離(li)傳輸。當然，現在的(de)(de)電(dian)(dian)(dian)壓不(bu)能(neng)用(yong)于家庭和(he)辦公室。提(ti)供的(de)(de)電(dian)(dian)(dian)壓為(wei)大型(xing)工(gong)廠100,000V，建筑物6600V，家庭和(he)辦公室200V或(huo)100V。
