Answer:
The maximum potential is determined by the dielectric strength of the air which is surrounding the generator...
Explanation:
The maximal achievable potential is roughly equal to the sphere radius R multiplied by the electric field Emax at which corona discharges begin to form within the surrounding gas. For air at standard temperature and pressure (STP) the breakdown field is about 30 kV/cm.
