All,
This brings up a question that has been rattling around in my head for a
while now. Actually two questions.
1) How are the static gap distances arrived at and why do you(generic)
divide them up the way you do?
2) Does increasing and decreasing the distance of the gap have the ultimate
effect of moving the shorting point along the rising portion of the charging
cycle? Diagram is best viewed in Courier font.
