Electric arc in 0 gravity? Curved or straight?

Click For Summary
SUMMARY

The discussion centers on the behavior of electric arcs in different gravitational conditions, specifically whether they would form straight or curved paths in zero gravity. Participants agree that electric arcs curve due to the influence of electric field strength, gas density, and the type of gas involved. The concept of Paschen's law is introduced, indicating that the arc's path is influenced by the voltage applied and the distance between electrodes. It is concluded that while arcs generally curve under gravity, their shape is determined by various physical factors, including the electric field and gas properties.

The shape of arcs may be influenced by the relative alignment of the faces of the two electrodes .

Electrode faces which are both angled up do seem to produce upward curved arcs .

Did You see arc curving down? The heated air in the plasma rises up and the least resistance between electrodes remains through the plasma arc.

Yeah big one, but why?
Very long arc is shaped at air movement and the least resistance between electrodes remains through the plasma arc.
