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

通过外部电路就可以利用这一点来导通电流。

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

这样， 至少您不会主动通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通电，从而释放原本就炙手可热的氧气。

你已经通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.

后，他使电流以相反的方向流过电线，并看到针向另一个方向移动。

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气的依赖，尤其是不能通过削的通过波兰和乌克兰的运输管道来实。

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!

如果你想找到通过每个分支的电流， 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!

如果您想找到通过每个分支的电流，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，把它们都转向同一个方向，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和电压，所以您再次使用欧姆定律来计算通过每条导线的电流。

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，发对大脑的某个特定区域以特定的方向通电可以提高学生在数学谜语方面的表。

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，通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 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，实进出口保稳提质任务目标，助力稳经济稳产业链供应链。

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通过， 瞧，你可以制造一个可以举起汽车的强大电磁铁。

Inventing a viable electric light was hard, I mean, this is the typical incandescent design, which just involves passing electric current through a material making it so hot that it glows, less than 5% of the electrical energy comes out as light.

发明一种可行的电灯是很困难的, 我的意思是, 这是典型的白炽灯设计, 只需让电流通过某种材料，使其变得非常热，从而发光，只有不到5%的电能以光的形式出。
