Calculation of Electric Unit charge
Il-Tong Cheon
Abstract
Considering the stresses due to the vacuum fluctuation and the electric charge loaded over the surface of a spherical cavity, we estimate the maximum value of the charge. Since this value is independent of the cavity size and parameter free, it is regarded as the electric unit charge. Our result is Q= 1.55× 10-19 Coulomb which implies the relevant fine structure constant α=1/145.90.
