Re: [Phys-l] Sparks

Most high current density "sparks"...they may not be high current, and they may not spark, are plasmas rather then solid material.

JD makes the point about 'high' voltage sparks vs high current sparks.

Also note that each high current 'spark' follows a parabolic path, as
do the 'sparks' from July 4th 'sparklers'.

Hot metal droplets 'burn' as they fly through the air.
