121List of electrical engineering topics (alphabetical) — This page aims to list, alphabetically, all articles related to the specific discipline of electrical and electronics engineering. For a thematic list, please see List of electrical engineering topics. For the broad field of engineering, see List …
122Electrical element — Electrical elements are conceptual abstractions representing idealized electrical components, such as resistors, capacitors, and inductors, used in the analysis of electrical networks. Any electrical network can be analysed as multiple,… …
123Quiet PC — A quiet PC is a personal computer that makes little noise. Common uses for quiet PCs include video editing, sound mixing, home servers, and home theater PCs. A typical quiet PC uses quiet cooling and storage devices and energy efficient… …
124Coherer — Metal filings coherer The coherer was a primitive form of radio signal detector used in the first radio receivers during the wireless telegraphy era at the beginning of the twentieth century. Invented around 1890 by French scientist Édouard… …

126Voltage regulator tube — A voltage regulator tube (VR tube) is an electronic component used as a shunt regulator to hold a voltage constant at a pre determined level.Physically, these devices resemble vacuum tubes, but there are two main differences: * Their glass… …
127Gakken EX-System — The Gakken EX System is a series of educational electronics kits produced by Gakken in the late 1970s. The kits use denshi blocks (also known as electronic blocks ) to allow electronics experiments to be performed easily and safely. Over 25 years …
128Parametric oscillator — A parametric oscillator is a simple harmonic oscillator whose parameters (its resonance frequency omega and damping eta) vary in time in a defined wayAnother intuitive way of understanding a parametric oscillator is as follows: a parametric… …
