Aside from solar panels, pretty much all our electricity comes from spinning turbines.

除了太阳能电池板（依靠光电效应产生电势），大部分电能都来自于驱动的涡轮。

Right now, we're testing the phase shift due to an electric potential. That's amazing.

现，我们试基于电势的相位偏移, 真是太棒了。

Dr Stachewicz and Mr Ura experimented with different potential differences between needle and drum and eventually found one that resulted in meshes able to collect 50% more water than commercial versions, at no extra cost of production.

斯塔切薇兹博士和尤拉先生对针和滚筒之间的不同电势差进行了实验，最终找到了一种能比商业版本多收集50%水的网眼，而且不需要额外的生产成本。

Now, the interesting thing is that in addition to the pacemaker cells in the SA node, cells in the AV node, Bundle of His, and the Purkinje fibers, all have the ability to generate an electrical potential.

好了，有趣的是除窦房结起搏细胞以外，房室结、希氏束以及肯野纤维中的细胞都有形成电势的能力。

They are brought into existence in a subjective manner, but they then are independent action, and as such may continue to exist in duration within the physical field, according to their original electric potential.

它们以主观的方式被带入存，但是随后它们就是独立的行动，因此可以根据它们的初始电势能，物质场域内继续存一段时间。

None the less, we honor Volta's discovery today by naming our standard unit of electric potential " the volt."

尽管如此，我们如今仍然把电势的标准单位命名为 " 伏特" ，以此表彰他的。

So now we've paused on one motor action potential that's happening right now inside of your brain.

我们现暂停此时此刻你脑内的一个运动电势。

That is going to give you its potential at different areas on the map.

那将会给你展示地图上不同区域的电势。

She and her colleagues mimicked the design of simple but long-lasting Edison batteries, in which an electrolyte solution carries ions between positively charged nickel plates and negatively charged iron ones, creating an electrical potential that produces voltage.

她和她的同事们模仿了简单但持久耐用的爱迪生电池的设计，其中电解质溶液带电的镍板和带负电的铁板之间携带离子，从而产生产生电压的电势。

And the electrical potential for the whole reaction, called the standard cell potential, is just the sum of the standard potentials of both half reactions.

整个反应的电势，称为标准电池电势，就是两个半反应的标准电势之和。

Voltage is a measure of electrical potential energy, a type of energy related to an object's condition (and not its motion).

电压是电势能的量度， 是一种与物体状况（而非其运动）相关的能量。

To measure potential energy in an electric field, let’s imagine a positive test charge that’s moving between a capacitor’s plates.

要电场中量电势能， 我们可以想象一个试电荷电容器的两极板之间移动。

She can feel now that thing that the other girls say they've felt: the gentle, filling sensation as each cell in her skein pumps ions across membranes and the electric potential increases.

她现能感觉到其他女孩说她们感觉到的那种东西: 当她结中的每个细胞将离子泵过膜并且电势增加时, 那种温和的、充满的感觉。

Now electric potential energy, which is the potential energy a charged object has due to the electric force from another charged object.

现，电势能是一个带电物体由于另一个带电物体的电力而具有的势能。

And so in Physics 2 these are going to be, the most important one would be dealing with a scalar field of electric potential.

而物理2中，最重要的一项就是处理电势的标量场。

So far, we’ve learned how to calculate electric potential for capacitors – but can we apply the same ideas to point charges?

我们已经学会了如何计算电容器的电势——但我们能否将同样的概念应用于点电荷？

The graphs show the heart's OVERALL electrical potential, or voltage, as it changes over time during a cardiac cycle.

这些图形显示了心脏一个心动周期内随时间变化的总电势或电压。

And it works because of two main electrical principles: electric potential energy and capacitance.

它根据两个电气定律运行 两个主要的：电容和电势能。

Now, the units of electric potential are Joules over Coulombs, more commonly known as Volts.

电势的单位是焦耳 超过库仑，称为伏特。

We’re left with an equation that describes the electric potential generated by any point charge.

我们只剩下一个描述任意点电荷产生的电势的方程式。
