Phrase
electric potentials
电势
electric potentials is the plural of electric potential.
the electric potential energy per unit charge at a point in an electric field, measured in volts
- 1.
The potential energy per unit charge at a point in a static electric field.
静电场中某点的单位电荷的电势能
静电场中某点的单位电荷的电势能
In use
The electric potential at the negative terminal is lower than at the positive terminal.
Engineers calculated the electric potential before connecting the new device.
Electric potentials are often measured in volts.
the electric potential of [noun]
The electric potential of a capacitor depends on its charge.
电容器的电势取决于其电荷。
electric potential difference between [noun] and [noun]
电势差又称电压。
The electric potential difference between the two plates is 12 volts.
两个板之间的电势差为12伏特。
have [adjective] electric potential
This point has a higher electric potential than that point.
该点的电势比那点更高。
Common mistakes
The electric potential between the plates is 100 V.The potential difference between the plates is 100 V.
错误地将 'electric potential' 用于两点之间，应使用 'potential difference'（电位差）表示两点间的电势差值。
An electric potential exists at every point.Electric potential exists at every point.
不可数名词 'electric potential' 前不应使用不定冠词 'an'，去掉后更符合语法。
