Theoretical Derivation and Calculation of Electron Charge

In this paper, we propose an assumption of which the relation between electron and phonon is discussed and investigated based on the experiment of photon and electric interconverting with each other. We calculated the charge of a particular standing wave topology with Maxwells equation rotated in accordance space with the SO3 transformation. The derived charge value is 1.6035 10E19C around 0.0826% different from the experimental data, indicating the proposal is a promising theory to explain the origin of charge and spin of electron particle. Electron spin angular momentum comes from the orbital angular momentum of photon rotation (electromagnetic field rotation), and electron charge comes from photon, that is, the space-time rotation effect of electromagnetic wave.
