Van de Graaff Generator — Prelims Questions
A Van de Graaff generator is designed to produce a maximum potential of . If the radius of its metallic sphere is doubled, assuming all other factors remain constant and the dielectric strength of the surrounding medium is the limiting factor, what will be the new maximum potential?
Which of the following is NOT a fundamental principle utilized in the working of a Van de Graaff generator?
To achieve a higher maximum potential in a Van de Graaff generator, which of the following modifications would be most effective?
In a Van de Graaff generator, the charge transferred from the belt to the metallic sphere eventually resides on the outer surface of the sphere. This phenomenon is best explained by:
What is the primary function of the sharp points on the spray and collecting combs in a Van de Graaff generator?
A Van de Graaff generator is operating in air. If the generator is moved to a vacuum chamber, how would its maximum achievable potential likely change, assuming no other changes?
