But a cap only lets current flow while there is a difference in potential between the plates (not counting the minute leakage) once charged then it blocks it so your light-bulb, motor or whatever will not be getting any power. It has to be a changing potential ie AC or have a ripple on the supply.
Really.... when the Stabilant is sandwiched between two contacts, thus is in series with a load, an electric field is most likely produced similar to what happens with a capacitor (this is what you said cannot happen). In the Stabilants case it then becomes conductive, this aids the already conductive contact to conduct electricity. How that change from insulator to conductor happens is anyone's guess. I imagine they have designed it this way so that you can apply it to a multi pin connector, without adjacent pin conductivity issues. I wont tell you again, because you just wont believe it, it just works.
The potential across a cap when fully charged is supply voltage, this is its greatest potential difference, look at the graphs again. This is why it can be said that electron current flow does not occur through the dielectric. Maybe I have miss interpreted what you have said above? Yes when a capacitor is fully charged in series no circuit current is present.
This is where the Stabilant and capacitor are different. As the Stabilant moves into a conductive state from its initial field exposure, current flows and continues to do so. You also have to remember this product is to be used on already conductive surfaces. Like I said 1000 posts ago it fills tiny irregularities in the contact surface with a conductive material to aid in the conduction of electrons.
If you think its all tales and gimmicks don't trouble yourself with it, or go and buy some, or talk to some one else that uses it.
I was thinking before that you would be a really hard guy to work with;
Me - "Hey Tony, before you put that connector on you need to apply Stabilant, IAW the maintenance manual".
Tony - " Stabilant! That stuff doesn't work, what would the people that designed this thing know".
I reckon we would have a few 'I know better' procedure violations ha ha.
