I am trying to understand what happens on a sheet of
paper which does belong to "the real world." I am not
trying to model anything in 3dim with a 2dim model.

I convinced myself that, for the geometry chosen, the
paper is large enough to ignore the edge effect. See the
data on R which were posted yesterday under the
"calculating resistance" thread.

Can you ask a student to verify my experimental line?
What can be a better help than another experiment for the
same geometrical arrangement?
