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。
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.
电势，电位相对于电路中某一特定参照点或地面的属于电路中任何一点的单位电荷势能；电压。
The potential energy of a unit charge at any point in an electric circuit measured with respect to a specified reference point in the circuit or to ground; voltage.
电势可比作每单位电荷的位能。
Electric potential can be thought of as potential energy per unit charge.
