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。

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" ，以此表彰他的贡献。

We talked about electric potential energy and how it differs from electric potential, or voltage.

我们讨论了势能，以及它与 电延迟或张力。

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式进行测试， 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式。

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.

我们有一个描述延迟的方程 任何点电荷产生的电能。

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式。

This set-up allows a capacitor to store energy as electric potential energy.

这种安排允许电容器存储能量，在 一种势能电能。

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 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 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。

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——但我们可以将相同的想法应用于点电荷吗？

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。

But how can you determine how much electric potential energy a system has, and how much work it can do?

但是如何确定势能的大小 什么系统，能做多少工作？

So we can calculate the total electric potential possible, by integrating the negative electric field from to infinity to zero.

所以我们可以计算总势能， 通过将负场从零积分到无穷大。

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

我们学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？

In a capacitor, these lines run parallel to the plates, and each line that’s closer to the negative plate has a lower electric potential, or a lower voltage.

在电容器中， 这些线与极板平行， 每条线越靠近负极板， 电位越低，即电压越低。

We talked about electric potential energy and how it differs from electric potential, or voltage. We discussed how capacitors function and the factors that determine how much charge they hold.

我们讨论了电势能以及它与电势或电压的区别。我们讨论了电容器的工作原理以及决定它们容纳多少电荷的因素。

And this drop in potential energy, divided by the test charge's magnitude, gives us the electric potential energy difference per unit charge, also known as the electric potential.

势能随着测试电荷量的减少给我们带来了差异 单次充电中的电势能，又称电势。
