electrostatic characteristic
91Corona discharge — The corona discharge around a high voltage coil …
92Tube socket — Left to right: octal (top and bottom view), loctal, and miniature (top and side view) sockets. An early transistor socket and an IC socket are included for comparison. Tube sockets are electrical sockets into which vacuum tubes (also known as… …
93Stiction — is an informal portmanteau of the term static friction ( μ s), perhaps also influenced by the verb stick .Two solid objects pressing against each other (but not sliding) will require some threshold of force parallel to the surface of contact in… …
94Atmospheric electricity — is the regular diurnal variations of the Earth s atmospheric electromagnetic network (or, more broadly, any planet s electrical system in its layer of gases). The Earth’s surface, the ionosphere, and the atmosphere is known as the global… …
95Dense plasma focus — Plasma gun redirects here. For the science fiction weapon, see plasma weapon (fiction). A dense plasma focus (DPF) is a machine that produces, by electromagnetic acceleration and compression, a short lived plasma that is so hot and dense that it… …
96Wurlitzer electric piano — The Wurlitzer electric piano was one of a series of electromechanical stringless pianos manufactured and marketed by the Rudolph Wurlitzer Company, Corinth, Mississippi, U.S. and North Tonawanda, NY. Interestingly, the Wurlitzer company itself… …
97Plasma parameter — The plasma parameter is a dimensionless number, denoted by capital Lambda, Λ, which measures the average number of electrons contained within a Debye sphere (a sphere of radius the Debye length) in a plasma (but note that the word parameter is… …
98Flocking machine — The electrostatic flocking machine is a high voltage generator. The principle of work is that unlike charges attract each other.When the electrostatic flocking machine working, it generates high voltage and the flock has a negative charge. Put… …
99Lightning rod — A lightning rod (USA) or lightning conductor (UK) is a single component in a lightning protection system. In addition to rods placed at regular intervals on the highest portions of a structure, a lightning protection system typically includes a… …
