Hi!
I'm looking for a good but not-too-expensive van de Graaf Generator, as well
as some instruction on how to use one as an effective teaching tool.
Sargent-Welch sells one little 200,000 V van de Graaf type Generator for 166
dollars, and another big 400,000 V one for 529 dollars. I don't know if
it's really necessary to have a generator that produces 400,000 V, but I
also don't want to invest in a machine that isn't extremely effective in the
classroom. Anyone have any advice?
Thank you!
