Gas lighter. A gas lighter is a device used to ignite a gas stove burner. It is used for gas stoves which do not have automatic ignition systems. It uses a physical phenomenon which is called the piezo-electric effect to generate an electric spark that ignites the combustible gas from the stove’s burner.
The best-known application is the electric cigarette lighter: pressing the button causes a spring-loaded hammer to hit a piezoelectric crystal, producing a sufficiently high-voltage electric current that flows across a small spark gap, thus heating and igniting the gas. The portable sparkers used to ignite gas stoves work the same way, and many ...
Piezo ignition. Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters. [1] Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to mechanical deformation. It consists of a small, spring-loaded hammer ...
An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures. Michael Faraday described this phenomenon as "the beautiful flash of light attending the discharge of common ...
Corona discharges represent a significant power loss for electric utilities. Corona discharge from a spoon attached to the high voltage terminal of a Tesla coil. A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage.
A glow discharge is a plasma formed by the passage of electric current through a gas. It is often created by applying a voltage between two electrodes in a glass tube containing a low-pressure gas. When the voltage exceeds a value called the striking voltage, the gas ionization becomes self-sustaining, and the tube glows with a colored light.
The threat from electrical light in the later 1870s and 1880s drove this trend strongly. The gas industry did not cede the gas lighting market to electricity immediately, as the invention of the Welsbach mantle, a refractory mesh bag heated to incandescence by a mostly non-luminous flame within, dramatically increased the efficiency of gas ...
Thermal cutoff. An assortment of thermal fuses. A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (a thermal fuse), or may be reset manually or automatically (a thermal switch).
