Jul 12, 2022 at 16:12 comment added AccidentalTaylorExpansion @Peter-ReinstateMonica I guess it depends on how hard people are forced to move through the hallway. Do we assume the velocity of the stream at some distance from the obstruction is constant? In that case people would have to speed up to get through the obstruction. Do we assume people move at some maximal velocity? In that case people moving through the obstruction slow down and so does the entire hallway. The first case is similar to constant current supply and the last case is somewhat similar to a constant voltage supply.
Jul 12, 2022 at 12:29 comment added Peter - Reinstate Monica Paradoxically, people even speed up in your "resistor"! That's the phenomenon nasu commented on in his answer: In smaller cross sections (one resistor type is a length of wire with a small cross section) the individual electrons/people must move faster to achieve the same "flow rate"/current. The narrow corridor section is a "good conductor" (no obstacles) where a narrow cross section facilitates the resistance. One could also leave the corridor width as-is and fill the "resistor part" with sand or mud; that would imitate a bad conductor and indeed slow down individual people/"electrons".
