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。

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

不，我对那个电，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号换成可用的直电。

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

然后变器将其从直电换为电。

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。

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。

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 高压电比他倡导的直电更加危险。

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

哦，明白了。不了解，我对电和直电一无所知！

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换成电。

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。

I'm not talking rock music here, I'm talking electrical currents-alternating current-AC, and direct current-DC, the two ways in which electricity flows.

我不是在说摇滚音乐，我说的是电——电——AC，还有直电——DC，电动的两种方式。

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.

虽然大电源线上可能有直电，但其他一切都是电。

" D.C." stands for the District of Columbia.

” “直电。 ” 代表哥伦比亚特区。

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电而不是直电。

That's where you'll find the inverter, which is what converts that DC into AC and gives power to the engine.

有逆变器，它将直电换成电，给引擎提供动力。
