Questions-Positive charge generator etc. 212

I'll take your question at face value and answer it literally.

Do a Google search on "Vandegraff generator". (without the quotes) The above mentioned device will generate a "pure" charge.

After that start looking up the definitions of: charge Coulomb Coulomb per second Ampere Volt Watt volt-ampere Ohm electrostatics

After you've digested the above, get back to us. Good luck, have fun. ARM

Thank you, the vandegraff is part of what I was looking for. I take it that the vandegraff generator creates free electrons. I did not have any luck finding a relation between the power input (Watts) and the charge generated (Coulombs?) on the generator. Any advice would be great. (I've heard people reffer to the charge on the vandegraff in volts, but this doesn't seem to make sense unless they are talking about the difference btw the generator and earth or something.)

Also, is there a generator that does the opposite of the vandegraff? Free protons? Or can the vandegraff do this somhow? I'm looking for a powered electron sink.

In my calculations I wanted to set resistance as zero just for maximum current, is there a way to do that or should I just use a very small number? What resistance do the best superconductors have?

Thanks for any help

Hello, and if I understand your question correctly, you can connect two Vandegraff generators together in a manner such that one metal sphere on one generator will have a net positive charge and the other sphere will have a net negative charge. Sincerely,

A Van de Graaf generator does not "create" electrons, it collects them from a (usually) rubber belt, in much the same way as rubbing a balloon on your hair will build up a static electric charge on both the balloon and your hair. This charge is measured in coulombs. In the Van de Graaf generator, electrons are picked up by the belt at one end of the column and deposited at the other end, leaving one end with a net positive charge and the other with a net negative charge. The voltage between the two ends is a function of the amount of charge and the distance between the ends. A potential difference also exists between the generator and anything else around it, including the air.
