A vector diagram that shows a charge at rest on the surface of a
radiator which shows that there is no opposing vector at the center.
Then we have a radiator that is not in equilibrium. In that case i
would place a vector on the surface and another vector at the center.
Thus charges are in motion both on the outside and the inside of the
radiator.I base this on the reasoning that the inner resistance is
less
than 377 where an arc is produced at the ends. the idea that the
leading edge of current flow will reverse at the radiator ends and
oppose the trailing current is just beyond my thinking as you do not
have a closed circuit. I have not seen an illustration that shows
current that reverses upon itself in a open circuit.

Art, I am totally confused. I don't understand what you are
trying to say. Can you explain what you mean by the term
"Vector"? For something to be called a vector it must meet
a number of precise mathematical criteria. Note the
"Formal definition" at:
