electrical length
1Electrical length — In telecommunications, the electrical length is any of: #A transmission medium, its length expressed as a multiple or submultiple of the wavelength of a periodic electromagnetic or electrical signal propagating within the medium. The wavelength… …
2electrical length — elektrinis ilgis statusas T sritis fizika atitikmenys: angl. electrical length vok. elektrische Länge, f rus. электрическая длина, f pranc. longueur électrique, f …
3Electrical conduit — risers, seen inside fire resistance rated shaft, as seen entering bottom of a firestop. The firestop is made of firestop mortar on top, rockwool on the bottom. Raceways are used to protect cables from damage …
4Electrical wiring — in general refers to insulated conductors used to carry electricity, and associated devices. This article describes general aspects of electrical wiring as used to provide power in buildings and structures, commonly referred to as building wiring …
5Electrical resistance — is a ratio of the degree to which an object opposes an electric current through it, measured in Ohms. Its reciprocal quantity is electrical conductance measured in Siemens. Assuming a uniform current density, an object s electrical resistance is… …
6Electrical conductance — is a measure of how easily electricity flows along a certain path through an electrical element. The SI derived unit of conductance is the siemens (also called the mho , because it is the reciprocal of electrical resistance, measured in ohms).… …
7Electrical engineering — Electrical engineering, sometimes referred to as electrical and electronic engineering, is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable… …
8Electrical lengthening — is the modification of an aerial which is shorter than a whole number multiple of a quarter of the radiated wavelength, by means of a suitable electronic device, without changing the physical length of the aerial, in such a way that it… …
9Electrical tuning — is a mechanism by which vertebrates such as frogs and reptiles, which lack a long cochlea, discriminate sound. Mammals have long cochleae, and are able to distinguish different sounds by mechanisms such as mechanical tuning, in which the… …
10Length contraction — Length contraction, according to Hendrik Lorentz, is the physical phenomenon of a decrease in length detected by an observer in objects that travel at any non zero velocity relative to that observer. This contraction (more formally called Lorentz …
