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

通过外部电路就可以利用这点来导通电流。

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。

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，他使电流以相反的方向流过电线，并看到针向另方向移动。

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分支的电流， 以及每电阻器上的电压降， 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!

他拿了两根平行的线，把它们都转向方向，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电流超过这限度，它就会变成种有电阻的普通材料。

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。

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

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.

环路中电阻 1 上的压降将是电阻 40 欧姆乘以通过电阻的电流，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.

从而在两圆筒之间产生电位差，可以利用这点来驱动电流通过外部电路，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电流，被称为内在心脏传导系统。
