what do you mean by van de graft generater
Van De Graff generator is a is an electrostatic generator which is used to generate high potential differences. The voltage generated by the generator can be used for accelerating subatomic particles to high speed.
It can be used to demonstrate and check the presence of electric fields.
It was invented by American physicist Robert J. Van De Graff in 1929.
The principle of Van De Graff generator is that , it is designed on the basis of property that the charge given to a conductor which is hollow inside is transferred to the outer surface and scatters uniformly over it.
It is founded on the phenomenon of Corona discharge.
Hope it helps.
