That can be used to drive a current through an external circuit.

过外部电路就可以利用这点来导电流。

That way, at least you’re not actively sending a current through all that circuitry.

这样， 至少您不会主动过所有电路发送电流。

The new method involves passing a current through a molten pool of iron oxide, which drives off the originally sought-after oxygen.

新方法的步骤则包括向熔炉里的氧化铁电，从而释放原本就炙手可热的氧气。

You've run the current through to heat it up to extraordinary temperatures, much higher than the sun.

你过电流将其加热到非常高的温度，比太阳高得多。

Then, he runs the current through the wire in the opposite direction, and sees the needle move the other way.

然后，他使电流以相反的方向流过电线，并看到针向另个方向移动。

Washington does not want Europe to increase its reliance on Russian gas, especially not by undercutting current transit routes through Poland and Ukraine.

华盛顿不希望欧洲增加对俄罗斯天然气的依赖，尤其是不能过削减现存的过波兰兰的运输管道来实现。

And when he ran a current through both wires in the opposite directions, the wires repelled each other!

当两根电线都朝正方向转动时，电线会相互排斥！

If you want to find the current through each branch, and the voltage drop across each resistor, you’re gonna need Gustav’s help!

如果你想找到过每个分支的电流， 以及每个电阻器上的电压降， 你将需要 Gustav 的帮助！

If you want to find the current through each branch, and the voltage drop across each resistor, you're gonna need Gustav's help!

如果您想找到过每个分支的电流，以及每个电阻器上的电压降，您将需要 Gustav 的帮助！

He took two parallel wires, ran a current through both of them in the same direction, and the wires attracted each other!

他拿了两根平行的线，把它们都转向同个方向，线就互相吸引了！

Since you know the resistance of, and voltage across, each resistor, you just use Ohm's Law again to calculate the current through each wire.

因为您知道每个电阻器的电阻电压，所以您再次使用欧姆定律来计算过每条导线的电流。

Researchers at Oxford University studied 15 student volunteers and found that passing a current through a specific brain region and in a particular direction improved performance in maths puzzles.

牛津大学的研究人员对15名学生志愿者进行了研究，发现对大脑的某个特定区域以特定的方向电可以提高学生在数学谜语方面的表现。

So pacemaker cells are, in a way, your heart's very own brain, generating the initial spark that sends a current through your heart's internal wiring system, known as the intrinsic cardiac conduction system.

所以起搏细胞在某种程度上是心脏自己的大脑，产生最初的火花，过心脏的内部线路系统发送电流，被称为内在心脏传导系统。

China will help foreign trade enterprises through current challenges and maintain steady and high-quality growth of the sector to stabilize the economy, industry chains and supply chains, according to a circular released by the State Council on May 26.

5 月 26 日，国务院办公厅印发《关于推动外贸保稳提质的意见》，帮扶外贸企业应对困难挑战，实现进出口保稳提质任务目标，助力稳济稳产业链供应链。

Naturally occurring magnets aren't powerful enough to lift up huge slabs of steel, but wrap an iron core with wires and run a current through and voila, you can create a powerful electromagnet that can lift cars.

自然产生的磁铁不足以举起巨大的钢板，但用电线包裹铁芯并让电流过， 瞧，你可以制造个可以举起汽车的强大电磁铁。
