在一般的电力变压器中，绕组电阻压降很小，可以忽略不计，因此在原边绕组中可以认为电压U1=E1。由于副边绕组开路，电流I2=0，它的端电压U2与感应电动势E2相等，即U2=E2。所以由上面的原、副边感应电动势公式得：
由此可见，变压器原边、副边的电流比与他们的匝数比或电压比成反比。例如一台变压器的匝数N1＜N2，是升压变压器，则电流I1＞I2；如果绕组匝数N1＞N2为***变压器，则电流I2＞I1。也就是说，电压高的一边电流小，而电压低的一边电流大
公式中K为原边电压U1和副边电压U2之比，这个K的数值称为变压器的变压比。
由上是表明，变压器原、副边绕组的电压比等于原、副绕组的匝数比，因此如果要原、副边绕组有不同的电压，只要改变他们的匝数即可。当N1＞N2时，K＞1，变压器***；当N1＜N2时，K＜1，变压器升压。
对于已经支撑的变压器而言，其K为定值，故副边电压和原边电压成正比，也就是说副边电压随着原边电压的升高而升高，降低而降低。但加载原边绕组两端的电压必须为额定值。因为，当外加电压比额定电压略有超过时，原边绕组中通过的电流将大大增加，如果把额定电压为220V的变压器错误的接到380V的线路上，则原绕组的电流将急剧增大，致使变压器烧毁。
把变压器的副边绕组负载接通后，在副边电路中有电流I2通过，此时，称变压器负载运行。由于副边绕组中电流I2也将在铁芯中产生磁通（即自感应现象），这种磁通对于原边电流所产生的磁通而言，是起去磁作用的，即铁芯中的磁通应为原边、副边绕组中电***生的磁通的合成。但在外加电压U1和电源频率f不变的条件下，由近似公式：
上式中可以看出，合成磁通Φ应基本保持不变。因此，随着I2出现，原边绕组中通过的电流I1将增加，这样才能使得原绕组中的磁通以免体校副绕组的磁通，另一面维持铁芯中的合成磁通保持不变。由此可知，变压器原边电流I1的大小是由副边电流I2的大小来决定的。
从能量观点来看，变压器原边线圈从电源吸取的功率P1应等于副边线圈的输出功率P2（忽略变压器的线圈电阻和磁通的传递损耗），即：
P1=P2或I1U1=I2U2
