A spark plug.The spark gap is at the bottom. A spark plug uses a spark gap to initiate combustion.The heat of the ionization trail, but more importantly, UV radiation and hot free electrons (both cause the formation of reactive free radicals) [citation needed] ignite a fuel-air mixture inside an internal combustion engine, or a burner in a furnace, oven, or stove.

A damped wave was an early method of radio transmission produced by the first radio transmitters (spark gap transmitters) which consisted of a series of damped radio waves. Information was carried on this signal by telegraphy, turning the transmitter on and off (on-off keying) to send messages in Morse code.
The intensity of the electric field for this gap is therefore 3.4 MV/m. The electric field needed to arc across the minimal-voltage gap is much greater than what is necessary to arc a gap of one metre. At large gaps (or large pd) Paschen's Law is known to fail. The Meek Criteria for breakdown is usually used for large gaps.
The pseudospark switch is a gas-filled tube capable of high speed switching.Pseudospark switches are functionally similar to triggered spark gaps.. Advantages of pseudospark switches include the ability to carry reverse currents (up to 100%), low pulse, high lifetime, and a high current rise of about 10 12 A/sec.

A trigatron is a type of triggerable spark gap switch designed for high current and high voltage (usually 10–100 kV and 20–100 kA, though devices in the mega-ampere range exist as well). It has very simple construction and in many cases is the lowest cost high energy switching option.
