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。

That potential difference is generated by the movement of ions, principally sodium and potassium across the membrane.

电势差是由离子运动造成的,特别是钠和钾的跨膜运动

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。

And the electrical energy is the product of the charge on the electron times the voltage which is the potential difference through which the electron was accelerated. And so this allows me to, by increasing the voltage, increase the energy on the electron.

电子能量是电子上的电荷数,乘以电压的结果,这是种内在的差距,通过它电子运动得以加速，这也让我，通过增强电压，来增加电子能量。
