Nearly all of us here have seen high voltage plasma in a vacuum like the CRT, but I want to know what would plasma behave like if it was in a high pressure state? Sorry I don't know about these things.

Thought that’s what an arc is? Someone correct me if that’s wrong. The higher the pressure the harder it is to strike, more voltage to break down a given distance. Obviously you need some sort of containment vessel, and an energy source, either directly between two electrodes, or via RF or microwaves to sustain it. I suppose the logical assumption it would be brighter hotter, or perhaps being more dense would look that way even it weren’t actually all that much hotter at the centre. Surely someone must have a more scientific explanation.

There is an optimum pressure, above and below which it is more difficult to strike a plasma.
