61Negative index metamaterials — A negative index metamaterial causes light to refract, or bend, differently than in more common positive refractive index materials. Negative index metamaterials or negative index materials (NIM) are artificial structures where the refractive… …
62PCOLA-SOQ — [1] is a method to gauge the effectiveness of testing a printed circuit board assembly (PCBA) in manufacturing to ensure the PCBA is devoid of manufacturing defects. Contents 1 PCBA Manufacturing Defect 2 PCBA Manufacturing Defect Universe …
63relaxation phenomenon — ▪ physics and chemistry Introduction in physics and chemistry, an effect related to the delay between the application of an external stress to a system that is, to an aggregation of matter and its response. It may occur in nuclear, atomic,… …
64DMX512 — A DMX splitter/buffer. It allows many devices that are controlled by DMX to be plugged into one controller, like a lighting console DMX512 (For Digital Multiplex with 512 pieces of information ) is a standard for digital communication networks… …
65Electricity — (from the Greek word ήλεκτρον, (elektron), meaning amber, and finally from New Latin ēlectricus , amber like ) is a general term that encompasses a variety of phenomena resulting from the presence and flow of electric charge. These include many… …
66Transformer — This article is about the electrical device. For the toy line franchise, see Transformers. For other uses, see Transformer (disambiguation). Pole mounted distribution transformer with center tapped secondary winding. This type of transformer is… …
67Tube sound — (or valve sound) is the characteristic sound associated with a vacuum tube based audio amplifiers. Some audiophiles prefer the sound that is produced by the distortion characteristics of tube based amplifiers. The audible significance of tube… …
68Relative static permittivity — The relative static permittivity (or static relative permittivity) of a material under given conditions is a measure of the extent to which it concentrates electrostatic lines of flux. It is the ratio of the amount of stored electrical energy… …
69Dynamic random access memory — (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically …
70Variable capacitor — Rotary variable capacitor A variable capacitor (also known as a variable air condenser ) is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C… …
