1) How do the electrons in a wire with 0 or negligible resistance arrange themselves in order to make the field in the wire 0?



2) The electric potential drop across a resistor is far more than compared to that in a wire. This means that the field in the resistor is greater than that in the wires. How does this happen inside a resistor?

          I really like this paper for this topic:
          https://www.tu-braunschweig.de/Medien-DB/ifdn-physik/ajp000782.pdf



          As the title says it is “A semiquantitative treatment of surface charges in DC circuits” (Rainer Mueller).



          Surface charges accumulate wherever there is a sudden change in the direction of the electric field lines from inside the wire to outside. Overall, you tend to get positive charge accumulating near the positive terminal and negative charges accumulating near the negative terminal, and you have both positive and negative charges accumulate on opposite sides of the wire near bends.



          Unfortunately, there is no one simple overall statement about the distribution. The charge distribution depends strongly on the geometry of the circuit layout. Circuit theory neglects the geometry of the circuit layout. So you need to use Maxwell’s equations which depend on the geometry.

                    One-line joke

                    A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't." "Venison's dear, isn't it?" (Jimmy Carr) "An escala...
