Another place where charge may be trapped is in the interior of the
coil form, again forming a capacitor with the exterior
windings. The charging system of a Tesla coil can't produce DC
charges in the secondary wire, that for DC is just a grounded wire.
Ionized air, with more charge of one type than of the other due
to rectification effects of corona, can deposit charges everywhere.
Charges deposited in the exterior or interior of the coil, separated
from the wire by a dielectric, become trapped there by a capacitive
effect.
What is an equidrive configuration in a Tesla coil?
