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

然后变器将其从直电转换为交电。

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

这就是直电，正是它面目。

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直电转换成交电。

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

直电这个词身就解释了它意思。

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

DC 是直电，和它名字一样，电子始终沿着同一方。

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

它利用直电在不到半小时时间内为汽车充电80%。

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。

An engine, for example, can be powered by direct current – which means that the electrons flow in one direction only.

例如，一台发机，可以由直电提供力，这意味着电子仅在一个方。

There a reason you're on direct current?

你们怎么还用直电？

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.

虽然大电源线可能有直电，但其他一切都是交电。

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。

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，我说是电——交电——AC，还有直电——DC，电两种方式。

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

到目前为止，我们主要讨论是 直电或直电。

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

感觉到自摩根压力 爱迪生启了一项计划 他要证明直电是最安全。

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

当您谈论直电路时，描述给定情况下电压和电非常简单。

New York City lit up with alternating current, which was five times that of direct current at that time.

纽约市用交电照亮，当时是直电五倍。

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

他是对，但当时技术更倾于更原始直电方法。

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

这是不幸，因为如今交电被认为是比直电更好电传输方法。

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 直电将会出 但这些电还需要输送。
