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

为了找出答案，们将次级线电压除以 初级线电压。

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

，们想知次级线电压与初级线电压相比如何。

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

次级线设计使其能够发出看起来像闪电电流。

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

因此，如果次级线回路数是初级线两倍，那么它电压将是初级线两倍。

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

如果次级线回路比初级线多，从而增加电压，则称为升压变压器。

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.

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

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.

次级线电压除以初级线电压等于次级线回路数除以线数 初级线回路。
