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.

这就是直流电，正是它的本来面目。

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 是直流电，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.

它利用直流电在不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，我说的是电流——交流电——AC，还有直流电——DC，电流动的两种方式。

It stands for transcranial direct current stimulation.

它代表经颅直流电刺激。

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 他要证明直流电是最安全的。

To access that, you need a First Direct current account.

要访问它，您需要一个 First Direct 活期账户。

Alternating current is considerably more efficient than direct current.

交流电比直流电效率高得多。

There a reason you're on direct current?

你们怎么还用直流电？

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流电，但其他一切都是交流电。

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

到目前为止，我们主要讨论的是 直流电或直流电。

The idea was that from this central station would flow all this direct current, but it also meant that it had to be transmitted.

通过中央发电站 直流电将会流出 但这些电还需要输送。

He was correct, but the technology available at the time simply favoured the more crude direct current method.

他是对的，但当时的技术更倾向于更原始的直流电方法。

This was unfortunate, as alternating current is recognized today as a better method of electric current delivery than direct current.

这是不幸的，因为如今交流电被认为是比直流电更好的电流传输方法。

When you talk about direct current circuits, describing the voltage and current in a given situation is pretty straightforward.

当您谈论直流电路时，描述给定情况下的电压和电流非常简单。

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.

我在这里说的不是摇滚音乐，我说的是电流——交流电AC和直流电DC，它们是电流流动的两种方式。
