In order to explain this, we should consider its working.
The Van De Graaff Generator has two metal comb one which is held near the end of belt known as emitter comb and another comb which is placed near the upper end of the belt known as collector comb.The emitter comb ,as it is given high positive potential with respect to earth ,the discharge of its action of its pointed ends set up as electric wind of positive charges.These positive charges are sprayed on the belt which carries them to the top .This make the shell of a Van De Graaff Generator positively charge.
But keep this is mind : The charge on the shell depends on the charge on the belt.
What else can I help you with?
Is it advisable to use wooden sphere for the dome of a van de graaf genarator?
Using a wooden sphere for the dome of a Van de Graaff generator is not advisable as wood is not a conductive material, which is necessary for the generator to function properly. A metal sphere or other conductive material would be more suitable for the dome of a Van de Graaff generator.
What type of attraction exists between the slight positive charge of a hydrogen atom and slight negative charge of a nearby atom?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.
What is a Vandergraph?
A Vandergraph is an apparatus that is used in the science track. It shows static electricity going through to an object or person. If a person, their hair stands up. If an object, you can see the stork of electricity. By Madeleine Rapisardi Mansfield High Australia
What type of bond makes water liquid?
Van der Waal forces determine the attractiveness of molecules to others outside of covalent and ionic bonds. For water, the dipole interaction between the slightly + hydrogen end of the molecules are attracted to the slightly - oxygen end.
What is an intermolecular force that affects all polar molecules?
Dipole-dipole interactions are intermolecular forces that affect all polar molecules. These forces result from the attraction between the positive end of one polar molecule and the negative end of another polar molecule.
Explain how a Van de Graaff generator builds up a static charge.?
A Van de Graaff generator uses a motor to transfer positive charge from a grounded metal sphere to a rubber belt continuously. The charge builds up on the metal sphere as the belt moves, creating a high voltage difference between the sphere and the belt due to the continuous transfer of charge.
Can van de graaff generator hold any amount of charge?
No, the Van de Graaff generator can produce a large amount of charge but does not hold the charge itself. The generator must be in motion in order to produce electricity. Once the motion stops, the charge is lost.
What is a Van Der Graph?
A Van de Graaff generator generates an electrostatic charge (like static electricity).
A pie pan is attached to a negatively charged Van de Graaff generatorThen the pie pan is removed from the areaDescribe the state of charge of the pie pan as this process is performed?
It is a positivly charged pan because the pan is negative in the first place and to negatives are a positive
Van de graaff water?

How was the van de graaff generator discovered?
robert j van de graaff
Who made Van de Graaff generator?
Robert .j. van de graaff
When was Jan van de Graaff born?
Jan van de Graaff was born in 1944.
When was Freek van de Graaff born?
Freek van de Graaff was born in 1944.
What is mechanisms of van de graaff generator?
The purpose of the Van de Graff generator was for it to be used to study static charge
Can negative ions be accelerated using van de graaf generator?
Yes, negative ions can be accelerated using a Van de Graaff generator. The generator can produce a high voltage difference that accelerates the ions, regardless of their charge. The ions will be repelled or attracted according to their charge, gaining kinetic energy in the process.
When was Robert Van de Graaff born?
Robert Van de Graaff was born on December 20, 1901.
