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:http://en.wikipedia.org/wiki/Vector_space

A vetor diagram in my mind evolves around Newtons laws
All forces (vectors) forces when summed must equal zero.
Whether their is a triange or a polygon of forces it always leaves a
gap
whuch thus provides a vector required to make he arrangement equal
zero
and in a state of equilibrium. The masters always followed this
aproach to determine if equilibrium
was present by vectorizing all the forces known within a arbitrary
border. They always came up with
an unclosed vector arrangement even tho it met the requirements of
equilibrium. So all filled in the gap
o arrive at the starting point and labelled this unknown vector that
they were forced to provide as the weak force required for equilibrium
to satisfy Newtons law.
