The textbook is a brief (thesis) presentation of the theory of electrostatics, equipped with visual illustrations (lines of tension, induction and equipotential surfaces), contains a detailed solution to the problems of electrostatics of charges in a vacuum and in the presence of dielectrics. Intended for university students studying general physics, and for teachers conducting seminars and practical classes in the “Electricity” section of the “General Physics” course. The manual can be useful to everyone who wants to learn how to solve problems in electrostatics on their own.
