Again Jorge Rebolledo He surprises us with the quality of one of his projects. In this case you have disassembled your Van der Graaff generator to explain how we can make it.
For those who do not know Van der Graaff generator it is, simplifying a lot, a unit that generates tension or very high potential differences. We are not going to go into detail about the reason for this device, if you want to know a little more about why it works, I recommend operation of a van der graaff.
As usual, we are "a little" less scientific and a little more technological and "practical."
Here are two pictures about the assembly and creation of the generator and one of its most important parts, the sphere.
For a good operation of the generator it is necessary to select a good pair of elements for friction so that many electrons are released. In this case, latex bands have been chosen.
With this 60 cm Van der Graaff he has achieved 3,8 cm sparks.
The next sheet shows How to create the Van der Graaff generator sphere, which, as Jorge shows, has made them with two cooking ladles, joining the two halves.
We hope it has been useful to you.
