The full energy regularization of point charge in classical   electrodynamics
  Convergence of the full energy (mass) of point charged particle by means of direct calculation is proved. The consideration is based on the strict solutions of nonlinear equations system of electrostatics and gravistatics in the classical field approach. Analytical calculation in the case of point charge mass of Markov's "Friedmon" M=e/(G^0.5) has confirmed. It is shown that mass defect caused by gravitational interaction leads to degradation of bare (phenomenological) mass and to its full vanishing from a total mass of system in the limit of point particle.
