Consider two series resistance chains, both with a 1K resistance
at the top, and one chain going to ground with an 11K resistance and
t'other going to ground with another 1K resistance, and then 12V applied
to both at the top.

When the switch is closed, how do the electrons and the electric field
"know"
that when they start moving that in the 11K case they only have to drop 1
volt
across the top 1K resistance, but in the case of the two 1K resistances in
series, they have to drop 6 volts across the top 1K resistance?
