They make contact with the non-metal part of an electric circuit (those protein wires).

它们与电路的非金属部分（那些蛋白质线）接触。

SHERI FINK: But electricity is all about circuits.

谢里·芬克：但是电与电路有。

Dopamine is intimately involved in that circuitry.

多巴胺与该电路密。

GREENFIELD: This reward circuitry is as old as time.

GREENFIELD：这个奖励电路与时间一样古老。

This is known as an ammeter, and it measures the current in Amperes by connecting in series with the circuit.

这被为电流表，通过与电路串联测量安培电流。

First, you'll notice that the magnetic field coming from our wire is parallel to the circle at every point.

首先，您会注自我们导线的磁场在每个点都与电路平行。

And unlike a digital circuit an electron can be doing all sorts of things at once.

与数字电路不同，电子可以同时做各种各样的事情。

When they reach the anode, these ions are united with electrons supplied by the external circuit and lithium atoms are thus re-formed.

当它们达阳极时，这些离子与外部电路提供的电子结合，从而重新形成锂原子。

There's an enormous number of circuit-building methods that I'd love to go over with you, but we're going to stick to the basics, which you'll use in every circuit problem you'll encounter.

我很乐与您讨论大量电路构建方法，但我们将坚持基础知识，您将在遇的任何电路问题中使用它们。

But since the current must divide equally into each of the different paths, we're left with two bulbs that have the same amount of current flowing through them that the single bulb circuit had!

但是因为电流必须在每条不同的路径中平均分配，所以两个灯流过的电流与单个灯电路的电流同！

But since the current must divide equally into each of the different paths, we’re left with two bulbs that have the same amount of current flowing through them that the single bulb circuit had!

但是由于电流必须平均分配每条不同的路径中， 所以我们只剩下两个灯泡， 它们流过的电流量与单个灯泡电路的电流量同！
