| Jul 23, 2021 at 10:20 | comment | added | KP99 | Charge is quantized, but one doesn't invoke such condition when calculating self energy in classical regime (Coulombic interaction doesn't imply charge quantisation). More correct interpretation comes from quantum electro dynamics, where self interaction comes from an electron interacting with its own virtual photons. Here charge is quantized, and involves both relativistic and quantum mechanical corrections to Coulombic interaction | |

| Jul 23, 2021 at 9:22 | comment | added | Uphill trajectory | @KP99 i.e. I want to consider building the charge configuration from $e$ charges. Then the energy should should still come to $$\gamma\frac{1}{4\pi\epsilon_0}\frac{e^2}{r}$$ where $\gamma$ is some factor | |
| Jul 23, 2021 at 9:13 | comment | added | Uphill trajectory | @KP99 but if you quantise charge, $dq$ can only as small as $e$ | |
| Jul 23, 2021 at 8:41 | comment | added | KP99 | $dq$ refers to any infinitesimal charge, not necessarily quantized charge $e$. It varies from system to system how small should $dq$ be. For an electron, you will have to assume $dq<<e$. For ordinary object $dq=e$ can be a good approximation. The point is dq must be much smaller than the total charge Q. | |
