To find out, we divide the voltage in the secondary coil by the voltage in the primary coil.

为了找出答案，我们将次级线圈中的以 初级线圈中的。

Now, we want to know how the voltage in the secondary coil compares to the voltage of the primary one.

现在，我们想知次级线圈中的与初级线圈中的相比如。

The secondary coil is designed so that it shoots out bursts of electricity that look like lightning bolts.

次级线圈的设计使其能够发出看起来像闪的流。

So if the secondary coil has twice as many loops as the primary coil, it'll have twice as much voltage.

因此，如果次级线圈的回路数是初级线圈的两倍，那么它的将是初级线圈的两倍。

If the secondary coil has more loops than the primary coil, so that it increases the voltage, that's called a step-up transformer.

如果次级线圈的回路比初级线圈多，从而增加，则称为升变器。

We can write this out as an equation for each coil separately, using a subscript P for the primary coil and a subscript S for the secondary coil.

我们可以将其分别写为每个线圈的方程式，使用下标 P 代表初级线圈，下标 S 代表次级线圈。

The voltage in the secondary coil divided by the voltage in the primary coil is equal to the number of loops in the secondary coil divided by the number of loops in the primary coil.

次级线圈中的以初级线圈中的等于次级线圈中的回路数以线圈数 初级线圈中的回路。
