What will happen to puffed rice when it is thrown onto the Van de Graff generator?
When puffed rice is thrown onto a Van de Graaff generator, the grains will be attracted to the generator due to static electricity buildup. The grains may stick to the surface of the generator momentarily before being repelled as the charge redistributes.
What is the magnitude of the electric field inside the dome of a charged VAN DE GRAFF generator?
The magnitude of the electric field inside a dome of a Van de Graaff generator is inversely proportional to the distance from the center of the dome. The field strength is typically strongest near the dome's surface and decreases as you move towards the center.
Why does a van der Graff generator repel a stack of tin foil plates?
A Van de Graaff generator can create a build-up of positive charge on the stack of tin foil plates. Since like charges repel each other, the positively charged plates will repel each other and spread out due to the electric force between them.
How do make static electricity?
Static electricity can be generated by a thing called a Van De Graff generator.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. Invented in 1929 by American physicist Robert J. Van de Graaff, the potential differences achieved in modern Van de Graaff generators can reach 5 megavolts (courtesy of wikipedia) See the Related Links Below for more details.
Why does your hair stand up when touching a charged Van de Graaff generator?
The large-radius sphere of a Van de Graff generator holds considerable charge before arc discharge occurs. The Van de Graff generator gathers negative charges and it is released into your body when you touch the sphere. We all know that negatives repel each other so since your hair is charged with negative electrons, they break away from each other (not lie flat on your head) in an effort to repel.
What is a Van de Graff generator?
The Van de Graff generator was named after Van de Graff, who invented it. A Van de Graff generator is a device used to store an enormous amount of electric charge (either positive or negative) on a metallic sphere so that a very strong electric field can be produced. This strong electric field can be used to accelerate charged particles like protons, alpha particles etc. In the Van de Graff generator, charges from an electric battery are separated and stored on a metallic sphere which is mounted on an insulating pillar.
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
When was John I. De Graff born?
John I. De Graff was born in 1783.
When did John I. De Graff die?
John I. De Graff died in 1848.
What is the best motor to use for a Van De Graff generator?
Most people use old vacuum cleaner motors.
What will happen to puffed rice when it is thrown onto the Van de Graff generator?
When puffed rice is thrown onto a Van de Graaff generator, the grains will be attracted to the generator due to static electricity buildup. The grains may stick to the surface of the generator momentarily before being repelled as the charge redistributes.
What has the author Esmond Vedder De Graff written?

Electrostatic generator van de graff for radiography operates in range of?
Electrons are stripped off a pad. Electrons are transferred to a metallic sphere. P.S Water_lilly_12@yahoo.com for help
Device used to create millions of volts?
Van De Graff generator for static electricity, a very large Tesla Coil could produce this level of voltage in AC electricity.
