Communication between the parameters of energy sources and plane physical field points

To date, in the design of various buildings and structures, it is important to model symbols of such physical fields as arise in the designed premises or territories. Geometrical apparatus for modeling such physical fields will solve a number of engineering problems related to determination of lighting of premises, propagation of noise from various types of energy sources, etc. Of particular interest to practice are a number of inverse problems, which are related to the determination of the capacities and position of point energy sources at given potentials, as well as the positions of points of the energy field. In this article, a study is carried out in which the restrictions that must be imposed on the position parameters of given points with the same potentials on the plane for point sources of energy of the same power are considered. Zones are determined that allow one to choose the position of the fifth point from a bunch of second-order curves passing through four given points so that the condition of five points belonging to one ellipse is fulfilled.
