Spark gap
A
spark gap consists of an arragement of two conducting
elements that control the movement of
electrons or
ions. It is composed of a set of
conductorss in which a disruptive and violent discharge of electromagnetic energy (known as a
current) passes from one node to the other node. The
dielectric medium that reduces the transmission of electricity between the two nodes reestablishes itself after the transition of the discharged current.
A spark plug uses a spark gap to initiate combustion.
