A Neumann boundary condition on a conductor surface amounts to specifying

  • A.the total charge on the conductor
  • B.the capacitance of the arrangement
  • C.the surface charge density
  • D.the potential of the conductor

Answer: C

The normal derivative of the potential is the normal field with a sign change, and the normal field at a conductor surface is the surface charge density over the permittivity. Prescribing one is therefore prescribing the other.
