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

全是直电，通器。

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

先生 你家里走的就是直电。

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。

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

然后器将其从直电转换为交电。

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

不，我对那个交电，直电一无所知！

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。

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。

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。

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。

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！

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动。

There a reason you're on direct current?

你们怎么还用直电？

Dc's kind of yesterday's news for this sort of thing.

直电比较落后。

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。

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

” “直电。 ” 代表哥伦比亚特区。

Alternating current is considerably more efficient than direct current.

交电比直电效率高得多。

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，但其他一切都是交电。

These are DC circuits, with resistors in series and parallel formations.

这些是直电路，串联电阻 和平行编队。

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。
