联合上一节的匝数比，可得到全耦合变压器的第二个重要特性：电压比等于线圈感值比的平方根，即
Every one of the preceding examples are within the nineteenth century, when "free of" was much significantly less widespread than "free from" In general. In Just about every situation, the phrase "free of" suggests "clear of," "untainted by," or simply "without." In distinction, "free from" suggests "liberated from" or "not oppressed by."
这个夏天，@故事茶话会 邀你一起穿越回那个天马行空的深夜，细数网文里的奇思妙想。
It Hence seems that "free white and twenty-just one" was for a substantial length of time in the initial 50 percent with the twentieth century a double-edged sword that may emphasize a (white) man or woman's arrival at full and sober maturity or even a (white) individual's arrogant declare to unchecked autonomy, Irrespective if the consequences performing exercises that autonomy might need on Other people.
绕组缠绕在磁性线性材料上制成的变压器称为线性变压器，所谓磁性线性材料是指磁导率为常数的材料，例如空气、塑料、胶木与木头等。实际上，绝大多数材料都是磁性线性的。有时候也将线性变压器称为空心变压器，尽管其磁心未必都是空气的。
首先是无穷大的电感值。即使我们采用世界上磁导率最高的铁芯材料，把铁芯的横截面做得很大，并且缠绕很多很多匝线圈，最终的电感值依然是有限的，依然存在励磁电流，只不过励磁电流比较小，在很多场合可以忽略而已。

如果电流从一个线圈的同名端流出，则在第二个线圈的同名端处电流流入，互感电压的参数极性为负。

现在，我们考虑把二次侧的负载 考虑进去，根据欧姆定律，我们求得二次侧电流为：
在空载时，负载 断开，二次电路开路，电流 ，所以此时，在一次电路中，电源输出的电流全部用来励磁：
