Miller effect works in a triode tube by placing a larger signal voltage
on the plate than on its grid. This increases the difference in number
of electrons between grid and plate.

The charge of a capacitor is the difference in number of electrons on
the two plates.



But a capacitor doesnot radiate.....the hole is getting deeper !


don't tell the designers of those funny little cross field antennas that!
their whole theory depends on capacitors creating a ratiating electric field
which then combines with their separately created magnetic field to create
an em wave.
