More electrons mean higher amperage, small wires burn because they cant move the needed electrons fast enough, it isn't resistance, all sound is, is pulses of electrical current, and once at the speaker it causes it to vibrate creating air compressions and decompressions, which you make into sound, now larger wires do not have a higher resistance, small and big wire gauges can have equal resistance the lower the gauge number the larger the size, small wires can't handle the amperage flow as for voltage that is the amount of work needed to pass through it, as for the ps question some conductors can be cooled, they are called superconductors and they have Absolutly zero resistance, there fore zero voltage drop will occur while being passed though the line all electricity is I'd the bumping of electrons and they transfer energy to each other. As go the conductor the more electrons in the valance ring of itself causes it to become less if a good conductor, to the point where it is an insulator.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
