Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Overhead Line
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. By contrast, battery electric buses and trains are charged at charging stations. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad The familiar diamond-shaped roller pantograph was devised and patented b ...

Electric Multiple Unit
An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail. EMUs are popular on commuter and suburban rail networks around the world due to their fast acceleration and pollution-free operation. Being quieter than diesel multiple units (DMUs) and locomotive-hauled trains, EMUs can operate later at night and more frequently without disturbing nearby residents. In addition, tunnel design for EMU trains is simpler as no provision is needed for exhausting fumes, although retrofitting existing limited-clearance tunnels to accommodate the ...

Batumi
Batumi (; ka, ბათუმი ) is the second largest city of Georgia and the capital of the Autonomous Republic of Adjara, located on the coast of the Black Sea in Georgia's southwest. It is situated in a subtropical zone at the foot of the Caucasus. Much of Batumi's economy revolves around tourism and gambling (it is nicknamed "The Las Vegas of the Black Sea"), but the city is also an important seaport and includes industries like shipbuilding, food processing and light manufacturing. Since 2010, Batumi has been transformed by the construction of modern high-rise buildings, as well as the restoration of classical 19th-century edifices lining its historic Old Town. History Early history Batumi is located on the site of the ancient Greek colony in Colchis called "''Bathus"'' or "''Bathys"'', derived from ( grc-gre, βαθύς λιμεν, ; or , ; lit. the 'deep harbour'). Under Hadrian (), it was converted into a fortified Roman port and later deserted for the fortress ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tbilisi
Tbilisi ( ; ka, თბილისი ), in some languages still known by its pre-1936 name Tiflis ( ), is the Capital city, capital and the List of cities and towns in Georgia (country), largest city of Georgia (country), Georgia, lying on the banks of the Kura (Caspian Sea), Kura River with a population of approximately 1.5 million people. Tbilisi was founded in the 5th century Anno Domini, AD by Vakhtang I of Iberia, and since then has served as the capital of various Georgian kingdoms and republics. Between 1801 and 1917, then part of the Russian Empire, Tiflis was the seat of the Caucasus Viceroyalty (1801–1917), Caucasus Viceroyalty, governing both the North Caucasus, northern and the Transcaucasia, southern parts of the Caucasus. Because of its location on the crossroads between Europe and Asia, and its proximity to the lucrative Silk Road, throughout history Tbilisi was a point of contention among various global powers. The city's location to this day ensures its p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poti
Poti ( ka, ფოთი ; Mingrelian: ფუთი; Laz: ჶაში/Faşi or ფაში/Paşi) is a port city in Georgia, located on the eastern Black Sea coast in the region of Samegrelo-Zemo Svaneti in the west of the country. Built near the site of the ancient Greek colony of Phasis and deriving its name from the same, the city has become a major port city and industrial center since the early 20th century. It is also home to a main naval base and the headquarters of the Georgian Navy. Etymology The name Poti is linked to Phasis, but the etymology is a matter of a scholarly dispute. "Phasis" () is first recorded in Hesiod's ''Theogony'' (c. 700 BC) as a name of the river, not a town. Since Erich Diehl, 1938, first suggested a non-Hellenic origin of the name and asserted that Phasis might have been a derivative of a local hydronym, several explanations have been proposed, linking the name to the Proto-Georgian-Zan ''*Poti'', Svan ''*Pasid'', and even to a Semitic word, ...
