这是因为当(dang)对相同(tong)长度(电(dian)(dian)阻)的(de)电(dian)(dian)线通电(dian)(dian)相同(tong)时(shi)(shi)间时(shi)(shi)，会产生与(yu)电(dian)(dian)流(liu)平方成正比的(de)热量(liang)。由于(yu)热量(liang)是逸出的(de)能量(liang)，因此是功率(lv)(lv)损耗(hao)。比如你(ni)需要3000W(瓦)的(de)功率(lv)(lv)，如果(guo)电(dian)(dian)压(ya)(ya)是100V，你(ni)就需要30A(安培)的(de)电(dian)(dian)流(liu)，但是如果(guo)电(dian)(dian)压(ya)(ya)是1000V，你(ni)只(zhi)需要3A的(de)电(dian)(dian)流(liu)。换句话说，如果(guo)电(dian)(dian)压(ya)(ya)增(zeng)加10倍，电(dian)(dian)流(liu)量(liang)将减少(shao)(shao)到(dao)1/10，由此产生的(de)功率(lv)(lv)损耗(hao)可(ke)以减少(shao)(shao)到(dao)1/100，或(huo)1/10的(de)平方。出于(yu)这个原因，非常(chang)高的(de)电(dian)(dian)压(ya)(ya)用(yong)(yong)于(yu)长距离(li)传输。当(dang)然，现在的(de)电(dian)(dian)压(ya)(ya)不能用(yong)(yong)于(yu)家庭(ting)(ting)和办公室。提供的(de)电(dian)(dian)压(ya)(ya)为大型工厂(chang)100,000V，建(jian)筑物6600V，家庭(ting)(ting)和办公室200V或(huo)100V。
