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

然后变流器将其从直流转换交流。

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

这就是直流，正是的本来面目。

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

们大多数都是把池里的直流转换成交流。

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

直流这个词本身就解释了的意思。

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

DC 是直流，的名字一样，子始终沿着同一方向流动。

It uses direct current to add up to 80% of the car's battery charge in less than half an hour.

利用直流在不到半小时的时间车充80%。

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，可以由直流提供动力，这意味着子仅在一个方向上流动。

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，我说的是流——交流——AC，还有直流——DC，流动的两种方式。

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

虽然大型输线路可能使用直流，但其他所有设备都使用交流。

The direct current part is very important for our story.

直流部分对我们的故事非常重要。

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

爱迪生力挺直流，而特斯拉则倡导交流。

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流而不是直流。

There a reason you're on direct current?

你们怎么还用直流？

Feeling the pressure from Morgan, Edison sets out on a mission to prove his direct current is the safest form of electricity.

感觉到来自摩根的压力 爱迪生启动了一项计划 他要证明直流是最安全的。

Alternating current is considerably more efficient than direct current.

交流比直流效率高得多。

Note that high-frequency electricity works differently from direct current or low-frequency 50 or 60 hertz household electricity.

请注意，高频与直流或低频50赫兹或60赫兹的家庭用工作方式不同。

Until now, we've mainly been talking about DC, or direct current.

到目前止，我们主要讨论的是 直流或直流。

From then on, the commercial competition between direct current and alternating current reached a white-hot stage.

从此，直流交流之间的商业竞争进入了白热化阶段。

The reality was that DC, direct current, simply wasn't up to the task.

事实是，直流根本无法胜任这项任务。

But Edison's dog in the fight, direct current, it is not good for sending electric power over long distances.

然而， 爱迪生力挺的直流，并不适合远距离输送力。
