81Transistor — For other uses, see Transistor (disambiguation). Assorted discrete transistors. Packages in order from top to bottom: TO 3, TO 126, TO 92, SOT 23 A transistor is a semiconductor device used to amplify and switch electronic signals and power. It… …
82Atomic battery — The terms atomic battery, nuclear battery, tritium battery and radioisotope generator are used to describe a device which uses the emissions from a radioactive isotope to generate electricity. Like nuclear reactors they generate electricity from… …
83Fair weather condition — concerns the electric field and the electric current in the air as well as the conductivity of the atmosphere. [ [http://science.nasa.gov/newhome/headlines/essd15jun99 1.htm Soaking in atmospheric electricity] ] It is the electromagnetic mode or… …
84Tetrode — A tetrode is an electronic device having four active electrodes. The term most commonly applies to a two grid vacuum tube. It has the three electrodes of a triode and an additional screen grid which significantly changes its behaviour. Grids The… …
85Epicureanism — Stephen Everson It is tempting to portray Epicureanism as the most straightforward, perhaps even simplistic, of the major dogmatic philosophical schools of the Hellenistic age. Starting from an atomic physics, according to which ‘the totality of… …
