the electrodes and the space between, considered as a unit: used in ignition systems.

A gap in an otherwise closed electric circuit across which a discharge occurs at a prescribed voltage. The discharge often causes ionization of the surrounding gas and thereby very high temperatures, and can be exploited, as in spark plugs, to ignite engine fuel in a combustion chamber.
