In the context of the classical electrodynamics, the physical sense of basic notions of electrostatics of dielectrics have been analyzed, in particular, sources and physical sense of vector field D are revealed, the correct condition of electric neutrality of the finite volume of dielectric medium is formulated. Different ways of derivation of electrostatics equations for a non-conducting isotropic medium are discussed. The integral equation is deduced for a vector E of the electrostatic-field intensity. A method of obtaining integral equations is proposed for vector fields of intensity E, dielectric displacement D and medium polarizability P.
