你可以操作线圈直接从110伏，交流内部电源线，或者，如果你发现它过热迅速，你可以与干预的线索，在一个串联电阻。

You can operate the coil directly from the 110-volt, alternating current house-supply line; or, if you find that it overheats rapidly, you can interpose a resistance in series with one of the leads.

当这些线圈被调节到合适的操作频率，电流就可以通过一个开关控制器转换给这些线圈。

The coils all get tuned to the right operating frequency and electricity is transferred to them using a switch-mode controller.
