The **electron-volt** ($\text{eV}$) is energy required to move an electron through a potential difference of one volt ($1\text{ eV}=1.60×10^{-19}\text{ J}$). One electron has a mass of $9.031×10^{-31}\text{ kg}$. The **electron-volt** ($\text{eV}$) is energy required to move an electron through a potential difference of one volt ($1\text{ eV}=1.60×10^{-19}\text{ J}$). One electron has a mass of $9.110×10^{-31}\text{ kg}$.
When $\Delta V=0$ the points are equipotential to each other, and no work is done moving between them. The images below outline equipotential lines — note that they are always **perpendicular** to electric field lines.
