The electron volt is not a unit of potential difference. 电子伏特(EV)不是,就是一单位的电子伏特(EV)。
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(EV)。
A unit of energy equal to the work done by an electron accelerated through a potential difference of 1 volt. 一个电子通过电位差为一伏特的电场所得到或减少的能量。
