FIELD: physics.
SUBSTANCE: model of a protected object is three-dimensional. A model of the protected area is made in form of a hollow thin-walled cone with a vertical axis along which is placed a telescopic rod which protrudes from the housing. The apex angle of the cone between its axis and side surface is equal to 41-55°.
EFFECT: demonstrating the principle of determining the height of a single lightning rod.
