الوصف
The motor driven van de graaff provides continuous supply of charge at high voltage (upto 200 KV). The diameter of metal dome is 180 mm and discharge sphere is 100 mm. The generator produces a spark length of approx. 3″. Supplied with standard accessories.
Features
- Function: It is designed to generate high voltages while maintaining low current levels, serving as an educational tool to illustrate concepts like electrostatics, conservation of charge, conduction, and ionization.
- Components: The device typically includes a large metallic dome (the collector sphere), a discharge sphere, a rubber or silicone belt, two metallic combs, and a motor or hand crank to drive the belt.
- Voltage Output: Hand-cranked models can produce potentials of up to 100,000 Volts or more, while other models can generate up to 400,000 Volts under good conditions.
- Mechanism: The charge is transferred to the metallic dome via a motor-driven or hand-cranked rubber belt and two metallic combs.
- Spark Gap: The generator can produce a visible spark, with some models creating a spark up to 3.2 inches long.
- Applications: Van de Graaff generators are commonly used in museums, school laboratories, and for classroom demonstrations.
