My brain is always full of charge! Pun intended. Okay, so my question here relates to voltage and charge, as my usual questions do.
1) So, let's take a computer power supply, for instance. You have the 12V, 5V, and 3.3V wires. The value of the current on these wires depends on the load the computer is subjected to. Take a 12V wire for example. How can current increase on this wire, let's say you increase it from 5A to 10A, without voltage increasing proportionally? I mean, the voltage lowers a bit as current increases (like what?). Resistance of the wire would only change a little bit due to the heat. Basically, why is this all contrary to Ohm's law? You have a 12V wire with adjustable current, yet voltage and resistance don't change very much and it all does not behave Ohmically. I can't wrap my head around it.
2) So electric fields connect and attract oppositely-charged particles. But do they also repel like-charged particles? How on earth would you draw that visually? You have the flux lines for protons and electrons being connected, but what would the flux lines look like for repelling charges?
3) Imagine nothing exists but a vacuum and two electrons. What is their behavior like? Do they constantly push away from each other, and do they push away at a constant velocity or one that decreases as they get farther away?
4) In a capacitor, as I read in Beaty's article here ( http://amasci.com/emotor/cap1.html ), I learned that one charge enters one plate and the electric field forces another charge out the other, causing a potential difference between the two plates. So in terms of a power supply unit, how the heck does this filter out ripple from high frequency switching?
4.1) So if you have one plate filled with electrons and the other plate filled with all protons, wouldn't this actually cause the protons in the actual aluminum separating the plates to all leave their atoms and go toward the proton plate, and all the electrons go to their electron plate?
5) So if two oppositely charged particles are next to each other, such as in an atom, wouldn't the voltage between them cause them to collide and come into contact? Why the heck don't those electrons end up hitting the nucleus if the atom? Is it for the same reason the moon doesn't hit the earth, inertia?
6) If I somehow got a backpack full of purely protons, could I suck the electrons away from everything I bring it by?
7) Is it possible for these questions to be answered in an understandable manner without me reading upon some other subject matter? If so, please point me toward that subject.
