Rob is absolutely correct here and I have just such tests shown on one or two of our
old video report tapes.  A piece of #24 wire 6 feet long attached to a resonator will
really swing resonance on down the scale!  An flaming white hot arc is a much larger
ionic surface conductor than such a piece of wire.  Again, the old hands-on folks have
"been there....done that".  One need not be a rocket scientist to figure this out real
quick if observant around bigger running systems.
