My memory of the big VdG at our school was it having a metal edge that scraped the belt. Generally, the stored charges on the Van de Graaff generator want to try to get into the ground.

Van De Graaff, is a type of electrostatic machine that can generate very high voltages millions of volts used to produce artificial lightning for demonstrations and experiments. Contact between two materials the belt and the roller is sufficient to start charges moving, and the machine is designed to make this a continuous process.

The charge spreads out over the surface of the dome until the voltage is great enough for electrical breakdown of the air to occur, initiating the process of a discharge or spark see our VDG gallery for photos of Van De Graaff sparks.

You'll even learn how to build your own Van de Graaff generator! But not all Van de Graaff generators come in this shape. If you turn on your headlights and then check your battery voltage, you will see that it remains relatively unchanged providing your battery is healthy.

The big picture in terms of how a Van de Graaff generator works is that the whole thing acts like an electromechanical pump for electric charge. The pipe is just a very simple way to provide the needed support. Related " ". I also just found this: Who Rides Passenger Trains in the U. A rubber or fabric belt F moving on a set of two rollers, one made of metal G and the other of an insulating material D such as plastic or resin.

Where do those electrons come from? Turns out huge seamless stainless steel spheres are used as garden ornaments and available on amazon or elsewhere for really cheaper than any custom made counterpart.

How Van de Graaff Generators Work

The film below explains the construction and functioning of a Van de Graaff generator. Thank you so much for writing this up. How the Van de Graaff generator works Demonstration The film explains the principle of the Van de Graaff generator, explains how to overcome problems when using it, and shows one simple but effective demonstration.

For example, your headlights may require 10 amps, but your windshield wipers may only require 4 amps.
