We also talked about transformers, and how they use mutual inductance to change voltage.

我还变压器，以及 它如何使用互感来改变电压。

Finally, we described how mutual inductance is used in wireless chargers.

最后，我描述如何 在无线充电器中使用互感。

Mutual inductance is also used in lots of other things, too – like wireless chargers, for example.

互感也被用其他方面——例如无线充电器。

All those voltage changes are made using transformers, which take advantage of something called mutual inductance, where a change in the current in one coil leads to a change in emf in another, nearby coil.

所有这些电压变化都是使用变压器进行的，变压器利用一种称为互感的东西，其中一个线圈中的电流变化会导致附近另一个线圈的电动势发生变化。
