[TCML] Arc Temperature

[Jim Lux]

Free air burning arcs run about 7000K...

As the current increases, the diameter of the arc channel increases to reduce the resistance, but the temperature remains about the same.

A 30mA spark is still 7000K, but not very big in diameter (fraction of a mm, I'd guess)

A lightning stroke at 20kA might be 1 cm in diameter, but is also at 7000K.
