Transient Suppression Devices and Principles - …

2013-7-1 · Silicon Carbide Varistors - Until the introduction of metal-oxide varistors, the most common type of “varistor” was made from specially processed silicon carbide. This material was very successfully applied in high-power, high-voltage surge arresters. However, the relatively low a values of this material produce one of two results.

Ceramic - The Full Wiki

A ceramic is an inorganic, non-metallic solid prepared by the action of heat and subsequent cooling. [1] Ceramic materials may have a crystalline or partly crystalline structure, or may be amorphous (e.g., a glass).Because most common ceramics are crystalline, the definition of ceramic is often restricted to inorganic crystalline materials, as opposed to the non-crystalline glasses.

Light-emitting diode - Wikipedia

2019-4-25 · A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recoine with electron holes, releasing energy in the form of photons. This effect is called electroluminescence.[5] The color of the light (corresponding to the energy of the photons) is determined by

Neon lamp - Wikipedia

2019-4-23 · A neon lamp (also neon glow lamp) is a miniature gas discharge lamp. The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a hode). When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces
