ELI5: Why does electricity "fork" or move in a "branch out" pattern?
gpt
Electricity takes **all** the paths at the same time.  However, the lower the resistance, the greater the fraction of the current that takes that path.  It turns out that a few paths have less resistance, and almost all the current takes those paths.  If there is a fork, then at that time there are two paths with equal resistance, and half the current takes each path.
