This form of application is illustratedin the use of the static iath, the breeze, and the spray as given offfrom metal electrodes, the high-frequency discharges from glass vacuumtubes, etc. The DISRUPTIVE discharges embrace the various sparks,—the long^short, and friction. The CONDUCTIVE discharge is derived from an electrified may be a continuous current flowing through a thin wire connectingthe knobs of an influence machine or joining the positive pole of abattery to the negative pole.
