My brain is more wired to think in terms of physics than electronics right now, so I have a simple question—and believe me I've tried to get this information from more than a dozen sources, but they usually don't spend any time explaining why they view it that way—or maybe they do but I am confused by the other explanations I've found. I am imagining I have a really good microscope and I can see where the electrons, protons, electric and magnetic fields are in a circuit that is in operation.
The context is thinking about the flow of charge in a common electronics schematic where a battery is the power source.
1. Is charge a reference to the electric field around electrons? Is it always that?
2. Is the '+' side of a battery (usually explained as the source of charge) actually a source of holes flowing out of the battery or it is the source of electrons flowing out?
Presumably the answers will imply whether the ground represents a sink or a source for charge.
