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.

现在，我们正在测试基于电势的相位偏移, 真是太棒了。

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

我们现在暂停在此时此刻正在你脑内的一个运动电势。

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为 " 伏特" ，以此表彰他的贡献。

This is the reaction's electrical potential, but to its friends, it's known simply as voltage.

这是反应的电势， 但对于它的朋友来说， 它被简单地称为电压。

Technically this height is called electrical potential energy, or voltage, but let's stick with the analogy.

从技术上讲，这个高度被称为电势能或电压，但我们继续使用类比。

Now let’s put our new expressions to the test and find the electric potential difference in a real scenario.

现在让我们对新表达进行测试， 并找出真实场景中的电势差。

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。

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在一个心动周期内随时间变化的总电势或电压。

Now I gotta point out here that the electrical potential of a redox reaction is related to its equilibrium constant.

现在我要在这里指出， 氧化还原反应的电势与其平衡常数有关。

Now let's put our new expressions to the test and find the electric potential difference in a real scenario.

现在让我们测试一下我们的新术语， 找出现实场景中的电势差。

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。

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。

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。

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

我们已经会了如何计算电容器的电势——但我们可以将相同的想法应用于点电荷吗？

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

我们会了计算电容器的电势，但是 我们可以将此应用于积分收费吗？

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

现在，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 the electric potential difference is also called voltage, which is another way of describing a drop in electric potential.

电势差也称为电压。 这只是描述低延迟的另一种方。

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，只是两个半反应的标准电势之和。

The electric potential depends on the electric field and the position, but it does not depend on the charge of the test charge.

电势取决于电场 和位置，并且不取决于测试货物的价值。
