CONDUCTORS AND INSULATORS reading
... Insulators are materials that have just the opposite effect on the flow of electrons. They do not let electrons flow very easily from one atom to another. Insulators are materials whose atoms have tightly bound electrons. These electrons are not free to roam around and be shared by neighboring atoms ...

In some actual X-ray tubes, the dark currents increase typically by an order of magnitude for the field increase of 5% [13]. Again, this example illustrates a striking difference between the DC and AC (transient) ...
