Why is the current flow arrow In the closed circuit picture pointing to the left and in the open circuit picture the no current flow arrow is pointing to the right?
That’s my electron/hole convention flow from positive to negative vs true electron flow from negative to positive. I use these conventions interchangeably depending on what I’m drawing, so the arrow directions really mean nothing…
When I’m drawing schematics for audio tube amplifiers then I’m careful to use electron flow convention from the cathode through the grid yo the plate. But for most circuit tracing it’s easier to imagine positive to negative flow even though that’s technically incorrect.
Many moons ago,, in the military, the most damning thing a senior electronics instructor could say about a young service member appearing before an academic review board, after months of specialized training, was:
“He (or she) doesn’t know the difference between a short and an open.”

Ouch!
Oh yes… it makes me crazy when I hear someone say “must be a short” when it’s obviously an open connection of some type.
