Tesla's "COIL FOR ELECTRO-MAGNETS".

   Voltage is a measure of electromotive force.   As you increase voltage you are increasing the accelerating field between charged bodies of mass.  The good thing is that in a capacitor your accelerating field is free.   This is the field between two bodies of mass where one is lacking electrons and the other is filled to the brim with electrons.  So if you flash charge a capacitor and the dielectric undergoes ionization the free electrons are accelerated for free.  These are dielectric electrons not cathode or anode electrons.  Depending on how far they are from the anode will determine what degree of acceleration they will acquire.   If the capacitor has discharged into the inductor before the electrons reach the anode they will induce a bunch of secondary electrons to flow in the inductor.   This why the natural media becomes conductive when it's rarified because it allows for increased acceleration or free flight time of the electrons.  The electric field always moves the electrons.  Even if it is the electric field of an electron next to it being pushed towards it.  As a contact moves towards a circuit to be energised it's electric field precedes it.  As the gap becomes smaller the electric field is more intense.   The electric field is so intense that it will ionize atoms by acclerating the electrons out of the orbitals way down to the inner most s orbital.  You see your contacts spark blue/violet.   Where is this light coming from?  Is it coming from the mass of the medium or is it coming from a coal burner hundreds of miles away?

 I like the thoughts there sparks.


To answer the questions here is my take. It all depends on whether you have 1 or two elements. If there is two elements or electrodes then the light is from one mass to the other mass but if there is one element then it comes from the density of the medium towards the one element or corona. Both stimulate the free charges in the medium into motion and radiance. Free charges are the matter of the medium. Air and other gases. The medium is what is in between the air or gases matter. The same can be applied to tubes as well I think. But since the tubes contain little matter we only see a glow emitted. This glow is the medium in excitation and rarefied. When the medium has matter in it it reacts strongly with the matter and excites the matter into radiance. This is as close to the operation of medium that I have gotten.

Sparks mentions accelerating electrons in the dielectric.  To me that suggests that he means current flow but in fact here is none.  What you have is deformed atoms under the external stress of the electric field.  Each atom becomes a mechanical spring that stores energy, but there is no electron flow.

The glow occurs because the intense electric field starts to strip electrons off of the gas molecules as part of the onset of current flow.  It's a very energetic process where a lot of power is being dissipated and electrons are jumping up and down in energy levels.  Some energetic electrons fall back into place around a given atom and in the process have to liberate their excess energy as photons.

The electrons that fall back increase in velocity due to either gravity or electrical forces intrinsic to the nucleus.  Mass is increased at the expense of energy.  Any particle that is experiencing an accelerating or braking force will have to radiate photons.  Photons are inertial currency.   It is obvious that a car crashing into a wall will have to convert some of it's inertia into radiance.  Sound waves-friction heating-kinetic energy transfer to the wall etc.   Less intuitive is that a mass undergoing acceleration will have to rid itself of the ,older inertia, by radiating photons.  This is why a particle will never reach the speed of light.  The particle can't rid itself of the old inertia because the photons just won't move away from the particle fast enough.

You are too far out for me Sparks and live in your own physics universe.
