I consider the electric field lines of any object over ten major
dimensions
from another object to be intrensically isotropic. The capacitance
developed by such an item is independent of all other items in the
universe.
(by theory) Thus the capacitance of the item is also isotropic. From
any
vantage point in space the capacitance is unchanging. The capacitance
is
related totally to the object itself (size) and no other object. In a
Tesla
coil situation the isotropic capcity is slightly altered by local coil
capacitive reactions, but the item still has capacity in an of itself.
