What is van de graafff generator....
Hemant Bhai please answer....
Mene YouTube pe dekha tha par ye hai kya.......

Answer:
Vande Graff generator is a machine which can produce large electrostatic potential difference. ... Initially the generator is started by giving the first comb a positive potential by a strong source of near about 10 4 Volt. Then an electric wind will be produced having positive charge.
answer.......
it is an electrostatic generator to produce very high potential of the order of millions of volt.
the resulting large electric fields (electron,protons,deutrons,and alpha particals) to high energies .
principle.
van de graaff generator based on two electrostatic phenomenon...
1). a sharp pointed conductor has large charge density.hence, surrounding air becomes conducting and produces discharge called Corona discharge.
2).when a charged conductor is brought in contact with a hollow conductor,then it transfer the charge to hollow conductor..the transferred charge resides on the outer surface of the hollow conductor.
