In this paper,we have proved that the electric potential creating by a unit of electric charge is a infinite small quantity.It is explained to adopt a proper attitude to use the ideal model of a dot charge,a surface charge and a linear charge.

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 $Q= 1.55\times 10^{-19}$ Coulomb which implies the relevant fine structure constant $α=1/145.90$.

This paper states that the induced charge should not be neglected in the electric Aharonov-Bohm effect. If the induced charge is taken into account, the interference pattern of the moving charge will not change with the potential difference between the two metal tubes. It means that the scale potential itself can not affect the phase of the moving charge, and the true factor affecting the phase of the moving charge is the energy of the system including the moving charge and the induced charge.

Electric charge has no direct meaning for strong interactions, yet is involved in the octet model in such a way that the size of the elementary unit of electric charge becomes tied to the topology of the group of strong interaction symmetries. This tie may indicate a relationship of electric charge to another kind of charge got directly from topology of the group.

It is conventionally believed that solutions of so called "free" Maxwell equations for \varrho=0 (density of charge) describe the free electromagnetic field in empty space (if one considers the free field as a field, whose flux lines neither begin nor end in a charge). We consider three types of regions: (i) "isolated charge-free" region (where all electric fields, generated by charges outside that particular region, are zero), for example, inside a hollow conductor of any shape or in a free-charge Universe; (ii) ``non-isolated charge-free" region (where all electric fields, generated by charges outside that particular region, are not zero) and (iii) "charge-neutral" region (where point charges exist but their algebraic sum is zero). The paper notes that there are two families of solutions: (1) In "isolated charge-free" regions electric free field does not exist in the context of Maxwell's equations, but there may exist a time-independent background magnetic field. (2) In both "charge-neutral" and "non-isolated charge-free" regions where the homogeneous condition \varrho=0 also holds, Maxwell's equation for electric field have non-zero solution, as in the conventional view, but this solution is not free field. We mention some implications related to free-electromagnetic fields and the simplest charge-neutral universe.

A few hundred years have passed since the discovery of electricity and electromagnetic fields, formulating them as Maxwell's equations, but the nature of an electric charge remains unknown. Why do particles with the same charge repel and opposing charges attract? Is the electric charge a primary intrinsic property of a particle? These questions cannot be answered until the nature of the electric charge is identified. The present study provides an explicit description of the gravitational constant G and the origin of electric charge will be inferred using generalized dimensional analysis. Key words: Electric charge, gravitational constant, dimensional analysis, particle mass change.
