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!
Cheers,
Terry
