Yes. Some of the larger units can create potential differences of several hundred thousand volts with ease, and the really big ones push several million volts. And they can do this with a good ability to deliver a big shot of current at that potential. A jolt from a Van de Graaf generator working in those ranges would be fatal.
Yes, by using a strong potential difference.
a van de graff generator
it creates an electric field around it self
It produces a very high voltage of the order of 107 V
A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate very high electrostatically stable voltages on a hollow metal globe on the top of the stand.
-- Wimshurst machine -- Van de Graaf generator
hes the guy who made the van de graaf
Bobbie van de Graaf was born in 1944.
Yes, by using a strong potential difference.
Karel van de Graaf was born on December 4, 1950, in Rotterdam, Zuid-Holland, Netherlands.

You can build one for the cost of a motor, PVC pipe, rollers, belt, some wire and a couple stainless steel salad bowls...That could be around $30. See the link for one person's DIY Van de Graaf. You can buy one from Edmund Scientific for $500
NO....a metallic dome must be used ,so that cahrges get accumulated on it...a wooden block(insulator) cannot do that..
The basic use of a Van de Graaf generator is to separate electric charges and build them up, frequently for demonstration purposes. A "big" version can be used to provide a burst of energy for generating X-rays, or for accelerating electrons or protons. The accelerated charges find some practical applications as well as some uses in scientific investigations. It's an electrostatic generator, and it will create a considerable difference of potential. Use the links below to read more about it and what we use it for.
"A Van de Graaff generator is an electrostatic machine which uses a moving belt to accumulate very high electrostatically stable voltages on a hollow metal globe. The potential differences achieved in modern Van de Graaff generators can reach 5 megavolts. The Van de Graaff generator can be thought of as a constant-current source connected in parallel with a capacitor and a very large electrical resistance."

No its the other way around
