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。

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。

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。

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？

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。

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。
