Re: [TCML] Spark gaps (again)

["Dex Dexter" <dexterlabs@xxxxxxxxxxx>]

The thing are the resistances of gap arc columns.
They are not the same I think becouse the impulse arc has the expansive evolution.
How much they  differ I don't know :( 
Any proof for that?

Cathode drop would be the same.
The arc column heats up in microseconds (viz camera flash), so I don't 
know that TC arcs are all that different than a free-burning arc.
