And we've talked about it before when we learned about Coulomb's law.

我们之前在了解定律时已经讨论它。

You could review Coulomb's laws videos in the physics playlist.

您可以在物理播放列表中查看定律视频。

The charges we talk about when we talk about electrons and protons, those are the coulomb forces.

当我们谈论电子和质子时，我们谈论的电荷就是。

We also discussed Coulomb’s law and how the force between charged particles is calculated using vectors.

我们还讨论了定律以及如何使用矢量计带电粒子之间的。

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

电势的单位是焦耳 ，称为伏特。

It’s just that, instead of using kilograms to find Newtons, here we’re using Coulombs to find Newtons.

只是，这里我们不是用千克来求牛顿， 而是用来求牛顿。

And in both cases the constant is 9 times 10 to the ninth Coulombs.

在这两种情况下， 常数都是 9 乘以 10 到第九。

This whole expression is known as Coulomb’s Law. And k is often known as the Coulomb’s Law constant.

这整个表达式被称为定律。 k 通常被称为定律常数。

For example, one electron has a charge of negative 1.6 times 10 to the negative 19th Coulombs.

一个电子的电荷为负1。6倍 用 10 次方减去 19 。

And k is often known as the Coulomb's Law constant.

定律。并且知道 K 是定律常数。

In this the fuel starts off in a small capsule and the Coulomb barrier is overcome by applying an external shock.

在这种情况下，燃料从一个小胶囊中开始，通施加外部冲击克服势垒。

But to calculate the number of Newtons, we’ll first need to measure the charge, denoted by “q”, in units called Coulombs.

但是要计牛顿数， 我们首先需要测量电荷， 用“q” 表示，单位称为。

Or in the case of electrons, when they get further away from a high energy state, the coulomb force is weaker, right?

或者就电子而言，当它们远离高能态时， 会变弱， 对吗？

From Coulomb’s law, we can calculate the magnitude of the force and find the direction based on the sign of the result.

根据定律， 我们可以计出的大小， 并根据结果的符号找到方向。

So we want to describe complex situations involving charged particles using more than just Coulomb's Law.

我们想描述复杂的状态，包括粒子 电荷，不仅是定律。

So one Coulomb of charge passing through that cross section of wire over one second is equal to one ampere of current.

因此，在一秒钟内通该导线横截面的一电荷等于一安培电流。

Capacitance uses units of Farads, with one Farad equal to one Coulomb per Volt.

电容以法拉为单位测量，其中一法拉等于 伏特。

To find F, you just have to use Coulomb's Law.

要计 F，你只需要使用定律。

Now, let's put Coulomb's Law to the test!

或减去，取决于吸引或 不和谐；现在让我们把定律！

In fact, you can plug the equation for Coulomb's Law into this equation, in place of capital F.

其实你可以输入一个定律方程 在这个方程中，代替了 F。
