I guess I should have specified. I'm looking for at the difference a radius has on a voltage breakdown. Right now I have a square edge, but needed know the minimum radius needed to avoid a breakdown.
I am trying to figure out the minimum radius needed to avoid voltage breakdown. I found this from a Physics website:
"The electric field near a conductor is inversely proportional to the radius of curvature of the surface."
So if I know the voltage and the distance between the 2 metal...
