Acoustical feedback energy system

My mind was running to the same examples.

Electrostatic charges build up upon the screen of a television cathode ray tube
(picture tube). Televisions have also, a high voltage transformer as part of that circuitry.

Do electrostatic charges also build up around an incandescent light bulb ? I have never
check this out.

Things start to get really interesting when we consider that the energy of an electrical circuit
is primarily carried in the field surrounding the wires, not in the motion of the electrons which
are bound to the wires. The wires are perhaps more like a kind of conduit which directs the fields.

Even more striking is the consideration that the wires are their selves a form of or complex
patterns of energy which we call physical matter.

CRT is not a perfect example to my reasoning. An electron source of an electron microscope is a better example of free/unbonded electrons I've meant. Electron microscope powered by a solar panel can't run out of unbonded electrons, isn't it? Will it run out of electrons, on a satellite, if electrons are beamed into outer space?

Here's a video of high-voltage arcing in vacuum. There's no conductor nor "valence electrons" to consider. Yet the bridge (consisting of electrons, of course) does build up: https://www.youtube.com/watch?v=WTPL-pm92eo Or you can give your own explanation, it will be interesting to hear.


Note that how it's two-way.


I'll add that physics invented "holes" to describe such behavior. It's like abstract holes on positively charged end strive to create a conductivity path. While in reality, as can be seen, there are electron bridges form at both ends.

If I may rephrase the question...

If we beamed electrons from a satellite which is within the vacuum of deep space,
could we reach a point at which the balance between the positive charge potential present
within the satellite exceeds the energy available to us (on board the satellite) required to
expel / beam more electrons from the satellite ?

addendum
Gota go, for now.

Yes, your rephrasing is correct, but it's a classical reasoning, and assumes that electron beam device borrows electrons from surrounding surfaces. Note that you can't measure electrostatic potential of a satellite as this requires a reference point. The ultimate question is whether or not electrons appear "out of nothing".
