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.
[1] [2] Spark-gap transmitters were the first type of radio transmitter, and were the main type used during the wireless telegraphy or "spark" era, the first three decades of radio, from 1887 to the end of World War I. [3] [4] German physicist Heinrich Hertz built the first experimental spark-gap transmitters in 1887, with which he proved the ...
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.

Lifeboats were equipped with spark gap transmitters such as the Marconi Type 241, c. 1920. [1] [2] These operated using Morse code on 500 kHz, the international distress frequency at the time. This frequency had the advantage of long range due to ground-wave propagation and was constantly monitored by all large ships at sea after the Titanic's ...

An air-gap flash is a photographic light source capable of producing sub-microsecond light flashes, allowing for (ultra) high-speed photography. This is achieved by a high-voltage (20 kV typically) electric discharge between two electrodes over the surface of a quartz (or glass) tube.
