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——交AC和直DC，它们是动的两种方式。

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

然后变器将其从直换为交。

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

这就是直，正是它的本来面目。

When an EV is plugged into a standard charging point, its systems convert AC into direct current (DC), which is what a battery needs to store electricity.

当动汽车插入标准充点时，其系统将交换为池存储力所需要的直(DC)。

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 爱迪生启动了划 他要证明直是最安全的。

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

它们多数都是把池里的直换成交。

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

它利用直在不到半小时的时间内为汽车充80%。

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——交——AC，还有直——DC，动的两种方式。

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

通过中央发站 直将会出 但这些还需要输送。

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

直这个词本身就解释了它的意思。

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

例如，台发动机，可以由直提供动力，这意味着子仅在个方向上动。

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

虽然型输线路可能使用直，但其他所有设备都使用交。

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

爱迪生力挺直，而特斯拉则倡导交。

More robust cables and transformers at sea to convert wind power from alternating into direct current, which can travel over long distances without big losses, enable more electricity to be generated farther away.

更坚固的海底缆和变压器可以将风能从交换为直，这样就可以在长距离传输中减少损耗，从而能够在更远的地方产生更多的力。

Direct current, of the kind which came to dominate electricity delivery systems in the late nineteenth century, consistently sends electricity in one direction along an electric grid.

直，就像在19世纪末主宰力输送系统的种，始终沿着网单向传输力。

This accounts  for the radiant energy of the aurora, which would be impossible if energy was transferred  through the magnetic field via direct currents.

这解释了极光的辐射能，如果能量通过直通过磁场传输， 这是不可能的。

And all of this money depended on his patented direct current system being standardised, being adopted as the standard current for electricity supply.

而所有这些资金都依赖于他的专利直系统成为标准，并被采纳为力供应的标准。

So it's directing the current from the lightning bolt right into the ground rather than into the tree itself.

因此，它将闪的直接引向地面，而不是引入树木本身。

There a reason you're on direct current?

你们怎么还用直？

However, after this, Edison began to become stubborn, insisting on using his own direct current system and refusing to accept Tesla's advice to switch to a more advanced, more stable, and more promising alternating current system.

然而，在此之后，爱迪生开始变得固执，坚持使用自己的直系统， 拒绝接受特斯拉的建议，改用更先进、更稳定、更有前途的交系统。
