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

为了找出答案，我级中电压除以 初级中电压。

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

现在，我想知级中电压与初级中电压相比如何。

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

级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，如果级回路数是初级两倍，那么它电压是初级两倍。

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

如果级回路比初级多，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.

我可以其分别写为每个方程式，使用下标 P 代表初级，下标 S 代表级。

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.

级中电压除以初级中电压等于级中回路数除以数 初级中回路。
