Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to find an estimated value (or range) for the current of an electric arc. I imagine this may be a function of the voltage producing the arc, the distance between the electrodes, and other parameters. If this is true, then take the voltage to be around 80kV and the distance between electrodes to be about an inch. I am just trying to get an estimate for an average arc current (in Amperes) in order to use this current in a theoretical Lorentz force calculation.

Also, is the arc current affected by the supply from which the voltage comes from? For example, if a power supply is providing lets say 1kV of voltage at a low current(<1A), if this current arcs across a centimeter gap, will the arc current be effected by the low current source?

Any help, comments, or suggestions would be greatly appreciated. Thanks so much!
