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 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. The lines of force between a straight electrode and a point electrode with opposite electrical charges. Lines of force between two straight electrodes with opposite charges and a ring between them, the Faraday cage, electrostatic shielding. The electric potential and the amount of charge accumulated in the generator. The electric potential and the work required to move an electric charge. The unit of natural electric charge and the quantity 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 extension of the spark in the Van de Graaff generator and the dielectric strength. Evaluating the extension of the spark produced by the generator and some factors that may interfere. The operating principle of the leaf electroscope and the distribution of charges in a conductor. Lighting a fluorescent lamp without contact with the generator. Lighting a neon lamp without contact with the generator. Making an electric fountain. Repelling paper strips with the generator. Simulating a lightning rod with the generator. Hair-raising sensation with the electrostatic generator. The turnstile effect of the electric wind with the generator, etc. Note: The generator is designed considering its use in different geographical locations, including coastal areas; its bearings are shielded, the motor is embedded to prevent contamination of the conveyor belt, and the motor belt is not exposed to protect the operator.
