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

通过外部路就可以利用这一点来通。

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路发送。

I was looking through current political cartoons, and this guy kept coming up.

我在浏览当前的政治漫画时，这个家伙经常出现。

And when you run a current through that wire, it creates a magnetic field.

当你通过线通时，它会生成一个磁场。

750 amps of current cut through this like butter.

- 750安培的像切黄油一样轻松穿过这里。

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，从而释放原本就炙手可热的氧气。

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

当两线都朝正方向转动时，线会相互排斥！

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，尤其是不能通过削减现存的通过波兰和乌克兰的运输管道来实现。

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

然后，他以相反的方向过线，并看到针向另一个方向移动。

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， 以及每个阻器上的压降， 你将需要 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!

他拿了两平行的线，把它们都转向同一个方向，线就互相吸引了！

And if you try and pass more current than that through the material, it's going to become a resistive material, a normal material.

而且， 如果你试图让材料通过的超过这个限度，它就会变成一种有阻的普通材料。

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.

因为您知道每个阻器的阻和压，所以您再次用欧姆定律来计算通过每条线的。

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，以及每个阻器上的压降，您将需要 Gustav 的帮助！

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通可以提高学生在数学谜语方面的表现。

And the drop across resistor 1 in the same loop would be the resistance, 40 Ohms, times the current through the resistor, which is 0.375 Amperes.

同一环路中阻 1 上的压降将是阻 40 欧姆乘以通过阻的，即 0。375 安培。

Thus creating a potential difference between the cylinders which could be harnessed to drive a current through an external circuit In effect and at an extremely small scale.

从而在两个圆筒之间产生位差，可以利用这一点来驱动通过外部路，实际上是在极小的尺度上实现的。

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，被称为内在心脏传系统。
