Van-de-Hoff's Generator working principle |
A Van de Graaff generator is an electrostatic generator. American physicist, Robert J. Van de Graaff was the person behind this invention. It uses a moving belt that accumulates charge on a hollow metal structure. This structure has a design of a globe, placed on the top of a column that is insulating in nature. Thus, it creates a very high electric potential in the order of a few million volts. This results in a very large electric field. We use this electric field to accelerate charged particles. |
