The book deals with problems of various levels of complexity, the solution of which, in one way or another, is based on the method of electrical images. Particular attention is paid to the problems of interaction of the charged ball with the conducting plane and two conducting charged balls. Most of the problems are original and for the first time at a fairly strict mathematical level are considered by the author. A number of tasks are directly related to natural (ball lightning problem) or technological (use of charged droplets in various devices) processes. Presented the results of original experiments on the study of electrostatic interaction in systems with the presence of electrical images Some results are published for the first time. The book is intended for a wide range of physicists (from students to teachers and specialists).
