Flat air condenser, facing of which are considered to be two identical disks is charged to high potential difference and after that is disconnected from the voltage source. In the center on condenser happens a breakdown and condenser discharges. Considering quasisteady discharge and neglecting homogeneity of the field on edges of the condenser, define stream of electromagnetic energy, flowing from the space between the facings. Discuss the phenomenon from the point of saving and transformation of energy.
