a flux of electrons or a flux of an absence of electrons?

Neither.

you are wrong here

You're looking at an electric field, or more precisely, the
potential difference between the two locations where the probe points
are. (The electric field is essentially the slope of the potential
difference.)

you are 100% right here, in a few lines a very concesive
compact explanation of maxwellian EM modeling phenomena,

you are smart


What you are doing in the scope is to "share" that potential difference

exactly, that was tha question

as FredFizzy correcty sensed the question, without a
bit of current going thro the scope in order to be
amplified, deflectings and stuff, the scope will be simply dead

that is in the circuit studied with a deflection grid inside the scope.
This is what deflects the electron beam in the scope.

lets make it simpler than that

conventionally the current goes from plus to minus, are
the electrons or the holes going from plus to minus?

what bears tha information or tha signal, the electrons
or absence of the electrons

i cen see the holes as an analogy to semiconducters
P and N dopped

what about a signal through an uniforme conductor
