What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.
前人们所做的就是他们说让我们确定,一个能量单位用来代表一单位电荷,加速穿过形成的一单位电势差,我们叫它电子伏特。
And what if I took a unit charge and I multiplied it times unit voltage, one volt?
如果我取个元负荷,让它乘上个电压单位,一伏特?
Or, in my favorite unit, 19.80 electron volts.
或者用我最喜欢的单位,就是19。80电子伏特。
The electron volt is not a unit of potential difference.
电子伏特不是,就是一单位的电子伏特。
What is the unit of potential difference? Volt.
势能差的单位是什么,伏特。
That is one electron volt.
就是一单位的电子伏特。
