It might not be what actually happens, but now I'm think of the voltage drop more like a hill; it must have a difference in high between two points, what doesn't mean that a few balls rolling down this hill would slow down or anything like that. Is that "right"?
I've been really confused on how electricity and circuits work
1. If eletrons "slow down" inside a resistor (or wire, I'm considering it's resistance to be ≠ 0) because of collisions with the lattice, then wouldn't the electrons pile up? The charges accumulating doesn't seem to be good.
2. Some...
