Explain the similarities and differences.
When the electric field in air exceeds a value of EDB = 3*10^6V/m (the dielectric strength), dielectric breakdown occurs and the air becomes ionized. If the electric field at the surface of a conductor exceeds this value, the ionization of the air will remove charge from the conductor until the electric field no longer exceeds 3*10^6V/m. What is the maximum charge that can be held on a conducting sphere in air in terms of the sphere's radius R and the dielectric strength of air EDB? (in terms, no specific numbers)
