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

为了找出答案，我们将次圈中的电除以 圈中的电。

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

现在，我们想知次圈中的电与圈中的电如何。

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

次圈的设计使其能够发出看起来像闪电的电流。

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

因此，如果次圈的回路数是圈的两倍，那么它的电将是圈的两倍。

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

如果次圈的回路圈多，从而增加电，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圈的方程式，使用下标 P 代表圈，下标 S 代表次圈。

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.

次圈中的电除以圈中的电等于次圈中的回路数除以圈数 圈中的回路。
