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

然后变流器将其从流电转换为交流电。

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

这流电，正它的本来面目。

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

它大多数都把电池里的流电转换成交流电。

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

流电这个词本身解释了它的意思。

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

DC 流电，和它的名字一样，电子始终沿着同一方向流。

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

它利用流电在不到半小时的时间内为汽车充电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，可以由流电提供力，这意味着电子仅在一个方向上流。

There a reason you're on direct current?

么还用流电？

Alternating current is considerably more efficient than direct current.

交流电比流电效率高得多。

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流电，但其他一切都交流电。

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不流电。

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.

我不在说摇滚音乐，我说的电流——交流电——AC，还有流电——DC，电流的两种方式。

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

到目前为止，我主要讨论的 流电或流电。

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 爱迪生启了一项计划 他要证明流电最安全的。

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

当您谈论流电路时，描述给定情况下的电压和电流非常简单。

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

纽约市用交流电照亮，当时流电的五倍。

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

他对的，但当时的技术更倾向于更原始的流电方法。

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

这不幸的，因为如今交流电被认为比流电更好的电流传输方法。

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 流电将会流出 但这些电还需要输送。
