# Physics/relating to a van da graff experiment

Question
thank you,
so if a 600kV, 60ľA VDG is leaking less then ~60ľA than it would still be 600kV, correct?
but if it is leaking more than the ~60ľA would it decrease the voltage suddenly when the ~60ľA leakage is reached OR would there be a gradual decrease in voltage correlated to the amperage leaked OR is it that the leakage is already around 60ľA to start of with and that is what is preventing the VDG charging over the 600kV and therefore any more leakage will already result in a lower voltage?
THANK YOU,
Gene

It would approach 60 microamps, not reduce to it.  The leakage depends on the voltage, the cleanliness of the insulators, the humidity...but most strongly upon the voltage.  So if your charging chain/band/pelletron can't support the discharge, it will come to equilibrium between charging and discharging, no matter which way you charge it.

##### Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

##### Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.
