Gaps (spark gaps)

A spark gap is a device used to create or control electrical sparks by placing two conductive electrodes with a gap between them. When a high voltage is applied across the gap, the electric field becomes strong enough to ionize the air or insulating medium, allowing a spark to jump across. Spark gaps are used in various applications such as timing circuits, lightning protection, and ignition systems, serving as switches or triggers that respond to specific voltage conditions by allowing electrical energy to discharge through the gap.
