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。

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。

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

对于大多数使用直电源的东西，所有能源都来自电池。

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！

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

先生 你家里走的就是直电。

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。

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

不，我对那个交电，直电一无所知！

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。

Well, most of them convert the direct current electricity from the batteries into an alternating current.

它们大多数都是把电池里的直电转换成交电。

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。

An engine, for example, can be powered by direct current – which means that the electrons flow in one direction only.

例如，一台发动机，可以由直电提供动力，这意味着电子仅在一个方向上动。

Finally, the third and most efficient one is the Direct Current charging station which does exactly what it says.

最后是第三个级别，也是最有效的一个，那就是直电充电站，它的充电效果正如字面意思。

DC appliances, and I think there's a real opportunity there, Chris.

AI：直电器，克里斯， 我认为那里有真正的机会。

While you may have direct current on big power lines, everything else is alternating current.

虽然大型输电线路可能使用直电，但其他所有设备都使用交电。

Precise stepper motors were traded in for continuous DC motors and encoders.

精密步进电机被换成了连续直电机和编码器。

Ok, I've got my meter here set to DC voltage.

好的，我把仪表调到了直电压档。

Edison was promoting direct current and Tesla was promoting alternating current.

爱迪生力挺直电，而特斯拉则倡导交电。

The magnetic field also  has been found to produce alternating currents rather than direct currents.

人们还发现磁场会产生交电而不是直电。
