"And no, the voltage is a maximum at the end of a radiator ... how can 
you have current flow at that point when there is no place for it to go???"

... depends on which end...

That's like saying a 2 inch air gap is going to break down at the same 
voltage as a 1 inch air gap because the first inch will break down and 
then the second.

And no, the voltage is a maximum at the end of a radiator ... how can 
you have current flow at that point when there is no place for it to go???
