Cidepe

Function

Intended for study, physics laboratory, physics experiments on: Electricity. The cathode electrode and the anode electrode in the Van de Graaff generator. The dielectric strength of a material. The electrical conductivity of a material. The conductivity of a gas. Gases, conductors of the third kind. Configurations of the lines of force between electrodes, the lightning rod, the Faraday cage and the coaxial cable. The electric field. Analogy between the Earth's gravitational field and the electric field, conservative fields. Michael Faraday, lines of force and the electric field vector between two electrodes. What is a line of force of an electric field. Properties of the lines of force of the electric field. The lines of force between a pair of straight and parallel electrodes with electric charges of opposite signs. The lines of force between a pair of point electrodes with electric charges of opposite signs. Lines of force between a ring electrode and a centered point electrode, with electric charges of opposite signs. Lines of force between a straight electrode and a point electrode with electric charges of opposite signs. Lines of force between two straight electrodes with charges of opposite signs and a ring between them, the Faraday cage, electrostatic shielding. Electric potential and the amount of charge accumulated in the generator. Electric potential and the work to displace an electric charge. The unit of natural electric charge and the amount of electric charge. Surface charge density. Measurement of the potential on the external surface of the generator sphere. Measurement of the surface charge density of the generator sphere. The extent of the spark in the Van de Graaff generator and the dielectric strength. Evaluation of the extent of the spark produced by the generator and some factors that may intervene. The operating principle of the foil electroscope and the distribution of charges in a conductor. Lighting a neon lamp without contact with the generator. Lighting a fluorescent lamp without contact with the generator. Making an electric fountain. Strips of paper that repel each other, with the generator. Simulating a lightning rod with the generator. Hair-raising with the electrostatic generator. The tourniquet, the effect of electric wind, with the generator, etc. Note: Generator designed taking into account its use in different geographical locations, including coastal areas, its bearings are shielded, the motor is built-in, preventing contamination of the load conveyor belt and the motor belt is not exposed, ensuring operator protection.
