| Oct 2, 2017 at 21:53 | comment | added | Leo Freeman | I don't know where the boundary of an electron is, if it even has one. But since the charge stays constant, as we know, and if the radius varied somehow, then the surface "voltage" would also vary with radius. I'm still trying to grasp the significance of a single electron having a "voltage", and at the same time, a collection of electrons on a metal sphere having another voltage. | |

| Oct 2, 2017 at 13:04 | comment | added | Ghosal_C | But the charge can also be modelled in a very illiterate way like a distribution like $\iiint\rho\psi{\psi}^{*}\mathrm{d}^3\vec{r}=e$ | |
| Oct 2, 2017 at 13:01 | comment | added | Leo Freeman | Not sure, but I thought ψ was the electron's "location" distribution, not its actual "size". I think it is generally agreed that electrons have a certain diameter, maybe < 10^18 m. Anyway, they are tiny, and so will carry a huge charge density, and therefore, Voltage? | |
| Oct 2, 2017 at 12:52 | comment | added | Ghosal_C | Is it possible to define the radius of an electron? An electron is always in a state of a distribution defined by $\psi$ | |
