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 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 in an electric field? Properties of lines of force in the electric field. Lines of force between a pair of straight, parallel electrodes with opposite electric charges. Lines of force between a pair of point electrodes with opposite electric charges. Lines of force between a ring electrode and a centered point electrode, with opposite electric charges. Lines of force between a straight electrode and a point electrode with opposite electric charges. Lines of force between two straight electrodes with opposite charges and a ring between them, the Faraday cage, and electrostatic shielding. Electric potential and the amount of charge accumulated in the generator. Electric potential and the work done to displace an electric charge. The natural unit of electric charge and the amount of electric charge. Surface charge density. Measuring the potential on the outer surface of the generator sphere. Measuring the surface charge density of the generator sphere. The extent of the spark in the Van de Graaff generator and its dielectric strength. Assessing 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. Repelling strips of paper 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: The electrostatic generator was designed with its use in different geographic locations, including coastal areas, in mind. Its bearings are shielded, the motor is recessed to prevent contamination of the cargo conveyor belt, and the motor belt is recessed to protect the operator.
