I wish I could grasp the resistive, capacitive or inductive Cometary Models
Well, you probably have more of a background to do so than I do...
My degrees served only as a prerequisite for positions. I can't say I needed the education to do my jobs.
The capacitive model is Wal Thornhill's: Comet is charged by induction in the outer reaches of it's orbit. As it moves toward the sun it enters environments of differing charges and attempts to equalize by discharging into the increasing positive field.
Again, I'm trying to describe Miles' model as I understand it. The comet is least charged in the outer reaches of its orbit. As it moves toward the sun the comet doesn't experience a more "positive" field but instead encounters an increased photon based charge field as per the inverse quad law distance (primarily) from the sun. Much of the charge field (photons) passes through the comet without interaction, though all the cometary matter is experiencing the increased charge field effects such as heating, ionization and breaking atomic bonds. The charge field also brings electrons, protons and small ions, but recognize that most of the work is being done by photons. Dust and ion tails are now forming. Each particle is recycling the increased charge field, physically driving neighboring particles away from each other through photon "pressure".
Electrons are pulled off and they , along with the matter that the electrons took with them form the ion coma and tail. It is suggested that a comet, in an overstressed state, will flare and even explode.
The comet experiences increased stress primarily in the form of heating - inductive as well as direct. After one or several thousand orbits the comets loose material, and the stresses build. Flares and explosions are no surprise.
Since I have only seen discreet components explode from and excess of current or component malfunction, I am developing a resistive comet hypothesis, just to exercise my mind. In short, the comet is electrically connected by plasma to where it was and to where it is going. I like circuits...
With each orbit, the comet goes through a severe electrical as well as heating and cooling cycle. It's a question of how well the materials which comprise the comet hold up.
Inductive comet is one that plays a part in it's charging as it moves through an electrical/magnetic field, setting it up to become a capacitive comet, or as it encounters magnetic fields along the way. Bumping into a cme with an iron comet would probably have an inductive component.
A CME event provides an increased number of highly charged (photon loaded) larger ions, adding to the stress.
The more spin aligned the charge field photons are, the stronger the magnetic effects. In his comet paper
http://milesmathis.com/comet.pdf, Miles notes that the long "curving" of the dust tails Iindicates the cumulative impact of the majority of spinning protons. The charge field is a bit more complicated considering whether a proton has a clockwise or counterclockwise spin.
