Hi Malcolm,


	Has a scope capture of the voltage and current across the gap of a primary
circuit (no secondary in place).  It shows a rather large voltage across
the gap initially and then a rather steady voltage waveform despite the
diminishing current after that.  This would tend to show exactly what you
are suggesting!
