Which inventor is famous for his contributions to the alternating current electrical system?

哪个发明家因对交电系统的贡献而出名？

No, I don't know anything about that AC DC!

不，我对那个交电，直电一无所知！

Next, a three-atom-thick layer of molybdenum disulfide converts that AC signal into usable DC electricity.

接下来，三原子厚的二硫化钼层将交信号转换成可用的直电。

All chargers take electricity from the grid, which uses an alternating current (AC).

所有的充电器都从电网中获取电能，而电网使用的是交电。

The inverters then convert it from dc direct current to ac alternating current.

然后变器将其从直电转换为交电。

It's just, it's just a direct current, is exactly what it is.

这就是直电，正是它的本来面目。

It's all dc power, it runs through into the inverters.

全是直电，通向变器。

Edison used all sorts of dirty tricks to try to discredit AC.

爱迪生用尽了各种肮脏伎俩试图败坏交电的名声。

For most things that run on DC, that's from the battery to whatever it's powering.

对于多数使用直电源的东西，所有能源都来自电池。

That direct current and, and the word direct means just that, and that's exactly what it is.

直电这个词本身就解释了它的意思。

Tesla has developed a new form of electricity known as " alternating current" , or " AC" .

特斯拉发明了一种新的电力形式称作" 交电" 简称AC。

Oh, I see. No, I don't know anything about that ACDC!

哦，明白了。不了解，我对交电和直电一无所知！

AC has a very high voltage, and is lethal.

交电电压很高 而且致命。

It doesn't have any electrical light during the day. No lights, no HVAC system, and barely a utility bill.

白天不会消耗电光源。没有光，没有高压交电系统，几乎不会收到物业账单。

But Edison believes that higher voltage AC is more dangerous than the direct current electric standard he's pioneered.

但爱迪生认为 高压交电比他倡导的直电更加危险。

You, sir. You have DC running through your home.

先生 你家里走的就是直电。

The electrons that move along an alternating current, on the other hand, periodically and consistently change direction.

另一方面，在交电中移动的电子会周期性地、持续地改变方向。

Its basic principle is the alternating current, for which we have Nikola Tesla to thank more than a century ago.

它的基本原理是交电，这个我们需要感谢一个多世纪前的尼古拉·特斯拉。

So there's a little converter in there and it's designed so it doesn't care what frequency the AC input is.

所以机器里面有一个小型转换器，它是特制的，因而不用担心交电的输入频率。

In DC, or direct current, is exactly what it sounds like, the electrons go directly where they're headed without backtracking.

DC 是直电，和它的名字一样，电子始终沿着同一方向动。
