Spark Discharge
</dt>
That type of gaseous
electrical discharge in which the charge transfer occurs intermittently
along a relatively constricted path of high ion density, resulting in high luminosity.
It is of short duration and to be contrasted with the nonluminous point
discharge, with the diffuse corona
discharge, and also with the continuous arc
discharge.

The exact meaning to be attached to the term spark discharge varies
somewhat in the literature. It is frequently applied to just the transient
phase of the establishment of any arc discharge. A lightning discharge is a
large-scale spark discharge, though its very length introduces certain details
not found in laboratory short-spark processes. [[/a>|/a>
