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

然后变流器将其从直流电转换为交流电。

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

这就直流电，正它的本来面目。

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

它数都把电池里的直流电转换成交流电。

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

直流电这个词本身就解释了它的意思。

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

DC 直流电，和它的名字一样，电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.

它利用直流电到半小时的时间内为汽车充电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，可以由直流电提供动力，这意味着电子仅一个方向上流动。

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.

我说摇滚音乐，我说的电流——交流电——AC，还有直流电——DC，电流动的两种方式。

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

虽然型输电线路可能使用直流电，但其他所有设备都使用交流电。

The direct current part is very important for our story.

直流电部分对我的故事非常重要。

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

爱迪生力挺直流电，而特斯拉则倡导交流电。

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

人还发现磁场会产生交流电而直流电。

There a reason you're on direct current?

你怎么还用直流电？

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 他要证明直流电最安全的。

Alternating current is considerably more efficient than direct current.

交流电比直流电效率高得。

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

请注意，高频电与直流电或低频50赫兹或60赫兹的家庭用电工作方式同。

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

到目前为止，我主要讨论的 直流电或直流电。

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

从此，直流电和交流电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，直流电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， 爱迪生力挺的直流电，并适合远距离输送电力。
