We present a description of Coulomb's constant using only fundamental measures (i.e., Planck Units defined without reference to ). Existing expressions often contain terms that are themselves defined as a function of Coulomb's constant. The goal herein is to provide new definitions with a term...
Is 1 coulomb a lot, in terms of electrons? Yes! One coulomb is a lot of electrons. The charge on a single electron is only 1.602x10^-19 C, so it takes many electrons to have a single coulomb of charge. Electric Charge Anelectric chargeis a fundamental property of matter, just like ...
C. Schieve Part of the book series: Fundamental Theories of Physics ((FTPH,volume 103)) 339 Accesses Abstract This chapter is both a continuation and generalization of the results of the preceding one, in that the two-body system with Coulomb potential, V = - \frac{k}{\rho }, (...
After many centuries, in 1785, Charles Augustin de Coulomb who is a French physicist published the actual mathematical relation between two electrically charged bodies and derived an equation for repulsion or attraction force between them. This fundamental relation is most popularly known as Coulomb’s...

, in Calculations in Fundamental Physics: Electricity and Magnetism, 1971 Publisher Summary Coulomb's law states that the force F between two point charges, Q1 and Q2, in a vacuum is proportional to their product and inversely proportional to the square of their distance apart r. Each charge ...

A particle suspended in the gas phase gains charge when an ion attaches to its surface. It is assumed that all the ions reaching the surface are captured by the particle. Impact charging (field charging) and diffusion charging are two mechanisms to bring ions to the particle surface. The for...
2D radius-vector r in the xy plane is also shown. Full size image As we pointed out above, the dielectric screening of Coulomb interaction plays the most fundamental role in semiconductors, determining, for instance, the exciton binding energy. On the other hand, it has been shown27 that ...
In previous posts I describedelectric chargeandelectric current. Electric charge is a thing carried by fundamental particles: electrons and protons. Electrons carry 1e of charge, and protons carry -1e of charge. When we talk of the “charge” of an aggregate object, we’re measuring the sum...
