Coulomb
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). In the present version of the SI it is equal to the electric charge delivered by a 1 ampere constant current in 1 second and to elementary charges, , (about ). Name and history By 1878, the British Association for the Advancement of Science had defined the volt, ohm, and farad, but not the coulomb. In 1881, the International Electrical Congress, now the International Electrotechnical Commission (IEC), approved the volt as the unit for electromotive force, the ampere as the unit for electric current, and the coulomb as the unit of electric charge. At that time, the volt was defined as the potential difference .e., what is nowadays called the "voltage (difference)"across a conductor when a current of one ampere dissipates one watt of power. The coulomb (later "absolute coulomb" or "abcoulomb" for disambiguation) was part of the EMU system of units. The "international coulo ...

Saint-Coulomb
Saint-Coulomb (; br, Sant-Kouloum) is a commune in the Ille-et-Vilaine department in Brittany in northwestern France. Population Inhabitants are called ''colombanais'' in French. History Its name comes from Saint Colomban, who came in the years 580 - 590. Accompanied by several monks, he crossed the English Channel and landed either on the ''Du Guesclin'' beach or a few hundreds meters further to the west. Beaches This commune has several beaches, very frequented by tourists in summer.

Coulomb Stress Transfer
Coulomb stress transfer is a seismic-related geological process of stress changes to surrounding material caused by local discrete deformation events. Using mapped displacements of the Earth's surface during earthquakes, the computed Coulomb stress changes suggest that the stress relieved during an earthquake not only dissipates but can also move up and down fault segments, concentrating and promoting subsequent tremors. Importantly, Coulomb stress changes have been applied to earthquake-forecasting models that have been used to assess potential hazards related to earthquake activity. Coulomb stress change The Coulomb failure criterion requires that the Coulomb stress exceeds a value σf defined by the shear stress τB, normal stress σB, pore pressure p, and coefficient of friction μ of a failure plane, such that It is also often assumed that changes in pore fluid pressure induced by changes in stress are proportional to the normal stress change across the fault plane. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coulomb Technologies
ChargePoint (formerly Coulomb Technologies) is an American electric vehicle infrastructure company based in Campbell, California. ChargePoint operates the largest online network of independently owned EV charging stations operating in 14 countries and makes the technology used in it. History ChargePoint was founded in 2007 as Coulomb Technologies by Richard Lowenthal, Dave Baxter, Harjinder Bhade and Praveen Mandal. In June 2017, ChargePoint took over 9,800 electric vehicle charging spots from GE. Prior to that point, ChargePoint managed 34,900 charging stations across Mexico, Australia, Canada, and the United States. The current CEO and president as of 2018 is Pasquale Romano. On November 28, 2018, ChargePoint raised $240 million. At the time, ChargePoint maintained 57,000 charging spots. In 2019, VW's Electrify America and ChargePoint agreed to provide common access to their US customers. Company reached 100,000 chargers in September 2019, while adding more than 2,000 ...

Coulomb Affair
The Coulomb Affair was a conflict between Emma and Alexis Coulomb, on one side, and Helena Blavatsky and the Theosophical Society, on the other. Blavatsky met Emma and Alex in 1871 in Cairo. They founded the short-lived Société Spirite. In August 1879, Emma and Alex contacted Blavatsky because they had financial problems. They were stranded in Sri Lanka, and Blavatsky helped them to get to Bombay and tried to find a job for them. As she could not find a job for them, she provided them with a position in the Theosophical Society, where they did various chores, such as cooking and gardening. In February 1884, Blavatsky and H. S. Olcott travelled to Europe. After their departure, a conflict between the Coulombs and the Theosophical Society escalated. The Coulombs tried to blackmail and threaten Blavatsky, whereupon Blavatsky dismissed them. When the theosophists inspected Blavatsky's room after the Coulombs had to leave, they found secret doors in her room . Alexis claimed that ...

Coulomb (crater)
Coulomb is a lunar impact crater that lies behind the northwestern limb, on the far side of the Moon. It is located to the west-southwest of the large crater Poczobutt, and northeast of Sarton. The rim of this crater is mildly eroded, but still retains a well-defined edge and displays some old terracing on the wide inner walls. The exterior of the crater also retains something of an outer rampart, extending for about a third of crater diameter. The satellite crater Coulomb V lies just beyond the west-northwest limb, while on the opposite side Coulomb J lies a short distance from the outer rim, forming a nearly symmetric pattern. The inner walls of the crater have only a few small impacts along the sides, with one near each of the aforementioned satellite craters. Within the sloping inner walls, the crater floor is remarkably level and nearly featureless, at least in comparison to the more rugged terrain that surrounds the crater. Only a few tiny craterlets mark this interior p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles-Augustin De Coulomb
Charles-Augustin de Coulomb (; ; 14 June 1736 – 23 August 1806) was a French officer, engineer, and physicist. He is best known as the eponymous discoverer of what is now called Coulomb's law, the description of the electrostatic force of attraction and repulsion. He also did important work on friction. The SI unit of electric charge, the coulomb, was named in his honor in 1880. Life Charles-Augustin de Coulomb was born in Angoulême, Angoumois county, France, to Henry Coulomb, an inspector of the royal demesne originally from Montpellier, and Catherine Bajet. He was baptised at the parish church of St. André. The family moved to Paris early in his childhood, and he studied at Collège Mazarin. His studies included philosophy, language and literature. He also received a good education in mathematics, astronomy, chemistry and botany. When his father suffered a financial setback, he was forced to leave Paris, and went to Montpellier. Coulomb submitted his first publication ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
