two bodies that are positive will repel one another, no matter what the magnitude of that charge is
Is a positive low voltage of electricity attracted to a positive high voltage electricity?
two bodies that are positive will repel one another, no matter what the magnitude of that charge is. Similarly two bodies that are negative will repel one another, no matter what the magnitude of the charge is.

I expect that the anode (which has a slight shortage of electrons) will be strongly attracted to the screen (which has a more severe shortage of electrons). This is because all of the remaining electrons in the anode (+) will be attracted towards the screen (+++). (..but I'm happy to be proven wrong on this!)
The sun is very very close to neutral. It has roughly the same number of electrons as it has protons. I say roughly because, with a mass of 2x1030 kg, the sun has approximately 1.2x1057 of each. So there is a very small chance that it is always perfectly matched, especially given the extreme temperatures. There could be a difference of a few million electrons or protons without really effecting anything, the sun is effectively neutral. If it contained only positive particles it would never have come together in the first place because the repulsion would be far stronger than the gravitational attraction.What gave you the impression that it is positive?
there is nothing neutral about anything that generates heat.
Quote from: Theboxthere is nothing neutral about anything that generates heat.A fire generates heat, but is electrically neutralA firefly generates light, but is electrically neutralA nuclear reactor generates heat, but is electrically neutral.A meteor crashing into Earth's atmosphere generates heat, but is electrically neutralWater freezing releases heat, but is electrically neutral Earth's core releases heat, but is electrically neutralA diesel engine generates heat, but is electrically neutralEven a wire which is generating heat due to an electric current flowing through it is almost exactly electrically neutral: If you turn off the electricity supply, there is almost no voltage left in the wire. So production of heat (conversion of one form of energy into another form of energy) does not require an electric charge.Some devices like the electric kettle use the flow of charge to generate heat (while keeping the total charge neutral).Are you perhaps thinking of some other measure like Power or Temperature which changes in a positive direction when something is producing heat?
The force on each proton should be equal and opposite of the force on each electron (equal charge magnitude, and same distance from the screen)

There will be a polarization effect, and in some rare scenarios it *might* be able to overcome the Coulombic repulsion, I would have to think about this more to see if I could come up with a case that resulted in attraction. This will depend on the actual amounts of charge on each object, the size and polarizability of the less positive object, and the distance between them (if the objects are close enough together, and the polarized object long enough, then the assumption that the negative and positive components have the same average distance fails)

Are you saying an objects positive energy is different?Look at ourselves, we contain electricity, but we contain also more negative than positive, hence attracted to the core and the much more positive of the ground.A+B=C=equilibriumA+B=C+A=AA+B=C-A=BGravity

It's kind of like saying that a heaviness is not attracted to another heaviness. The "heaviness" is an abstraction--it is one object attracting another, by virtue of their masses.Quote from: Thebox on 29/03/2015 14:09:06Are you saying an objects positive energy is different?Look at ourselves, we contain electricity, but we contain also more negative than positive, hence attracted to the core and the much more positive of the ground.A+B=C=equilibriumA+B=C+A=AA+B=C-A=BGravityYou really need to stop using that term, "positive energy" you are confusing yourself and others with it. We do contain electrical charges, but we are not more negative than positive. We are neutral! We are attracted to the Earth because of gravitation. It has nothing to do with charge or heat.
