Consider a building with many floors and lots of
stairwells. The doors to all the rooms in the building
are closed. The hallways and stairwells are chock full
of people walking purposely forward. To the extent
that a DC circuit is analogous to this situation, what in
the building is analogous to voltage?
a) Elevation.
b) The speed of a person.
c) The people flow rate (how many people
per minute go past a particular point in
the building).
