An electric current is the movement of an electric charge that carries electrons.

流是携带的荷的运动。

Just like with a corded phone, an electric current can rush through the power cord and not only destroy your device, but also hurt you.

就像有线话一样，流会通过源线，这样不仅会破坏设备，也会伤害到你。

Jupiter's gravity squeezes so tightly down here that electrons break free from the hydrogen atoms and flow freely throughout the liquid, generating an electric current.

在如此深处，木星的引力物质压缩得极为紧密，中被挤压出来，在液体中自由流动，而产生流。

Remember the dynamo; magnetism creates electric current.

还记得那发机吗？磁共生。

This electron flow is the electric current which is the reason for the battery's existence.

这种流就是流，这就是池存在的因。

The device they designed strips electrons from lactate, which creates a small electric current.

该设备能使乳酸中的脱离，而产生一小段流。

Denny, we're about to send a series of electric currents through your body.

Denny 我们会让一通流流过你的身体。

And here he's conducting experiments about electric currents.

在这里，他正在进行关于流的实验。

All have had what it takes to serve as a cathode for a battery: namely, an ability to have electrons ripped away from their atoms to be turned into electric current, leaving positively charged ions behind.

所有这些元素都具备作为池阴极的条件：即能中剥离出来，转化为流，留下带正的离。

When a neon sign is turned on, the electric current causes some of the neon atoms' electrons to accelerate and break free of their orbits, leaving behind positively charged ions.

当霓虹灯广告牌被打开，流使一些氖的加速并脱离轨道，留下大量带正荷的离。

And since the microwave oven is still going, electric current keeps bouncing back and forth between the sides of the grape, and across any steam or hot molecules carried up by the fire.

由于微波炉还在运作，荷还在两半葡萄之间来回反弹，经过了蒸汽或者热分，被火带到上方。

In the new study, the researchers designed an integrated photoelectronic processor to harness the advantages of both light, in the form of photons, and electrons, as found in electric currents, in an all-analog way.

在这项新研究中，研究人员设计了一种集成光处理器，以全模拟方式利用光形式的光和流中的的优势。

It has an electric motor attached to the wheels of the train that generates an electric current every time the train breaks, helping the train to not waste any energy.

它的车轮上装有一个动马达，火车每次刹停时，马达都会产生流，使火车不会浪费任何能量。

A special challenge was the design of an electronic device that can turn the constantly changing wind speed, and therefore varying power, into a steady electric current.

而对于设备亟待解决的一个难题是这样的设计可以把不断变化的风速及风速变化的功率，转变成稳定的流。

This means that instead of converting sunlight into electricity, metal-halide perovskites can operate in reverse, by emitting light in response to an electric current.

这意味着金属卤化物钙钛矿可以反向工作，不需要阳光转化为能，而是可以通过发光来响应流。

Electrodermal activity can mean a couple of things either the electrical output of nerves or how electric current travels as it passes over our skin.

皮活动有很多含义神经的流输出或者流通过我们皮肤时的传播方式。

Some use weak electric current, too weak to even feel, to gauge how fast your heart is beating and how fast you're breathing.

有的用微弱的流，微弱到甚至感觉不到，来测量你的心脏跳动速度和呼吸速度。

So when I bring the disc close to the magnetic track, a strong electric current begins to flow in the disc.

所以当我把圆盘靠近磁性轨道时，圆盘内会产生强大的流。

By sensing the change in electric current on the tag, the smartphone signals that it has detected the gas in question.

通过感应标签上的流变化，智能手机信号就会检测到问题气体。

I tried unsuccessfully to relax, but the electric current that seemed to be originating from somewhere in his body never slackened.

我试图放松下来，但没有成功，那股流似乎是他身上的某个地方传来的，未减缓过。
