Edison used all sorts of dirty tricks to try to discredit AC.

爱迪生用尽了各种肮脏伎俩试图败坏交流电名声。

Which inventor is famous for his contributions to the alternating current electrical system?

哪个发明家因对交流电系统贡献而出名？

For most things that run on DC, that's from the battery to whatever it's powering.

对于大多数使用直流电西，所有能都来自电池。

He begins using Tesla's alternating current in a series of demonstrations, hoping to scare the public about AC's power.

他开始使用特斯拉交流电进行一系列演示 希望吓退公众对交流电兴趣。

So there's a little converter in there and it's designed so it doesn't care what frequency the AC input is.

所以机器里面有一个小型转换器，它是特制，因而不用担心交流电输入频率。

Tesla wanted his company to work on this new idea of alternating current.

特斯拉希望他公司研究这种交流电法。

However, Tesla was unable to garner any serious interest in Alternating Currents.

然而，特斯拉未能引起人们对交流电浓厚兴趣。

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

这就是直流电，正是它本来面目。

Otherwise, the frequency of the AC power will speed up above 60 hertz.

否则，交流电频率将加快到60赫兹以上。

Edison was a proponent of DC (or Direct Current) and Tesla of AC (or Alternating Current).

爱迪生是 DC（或直流电）支持者， 特斯拉是 AC（或交流电）支持者。

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，当时是直流电五倍。

The electrons that move along an alternating current, on the other hand, periodically and consistently change direction.

另一方面，在交流电中移动电子会周期性地、持续地改变方向。

This invention led to Tesla winning the war on currents against Thomas Edison's DC and electrifying the world.

这项发明使特斯拉赢得了与托马斯·爱迪生直流电电流战争，并使世界电气化。

But Edison believes that higher voltage AC is more dangerous than the direct current electric standard he's pioneered.

但爱迪生认为 高压交流电比他倡导直流电更加危险。

And the same is true for the voltage in an AC circuit. .

交流电路中电压也是如此。

You could kill a man with half the energy, you go ac.

交流电可以用一半电力杀人。

Today, we learned about currents and voltages in AC circuits.

今天，我们了解 了交流电路中电流和电压。

Now free to pursue his own ideas, Tesla begins looking for an investor to back his AC technology.

现在特斯拉可以尽情追求自己理了 他开始要找一位愿意支持交流电技术投资人。

They clearly realized that all of this was brought by alternating current.

他们清楚地意识到，所有这些都是由交流电带来。

Now, let's say you're calculating the average power consumed by an AC circuit.

现在，假设您正在计算 交流电路消耗平均功率。
