Chairman Of The Board
The chairperson, also chairman, chairwoman or chair, is the presiding officer of an organized group such as a board, committee, or deliberative assembly. The person holding the office, who is typically elected or appointed by members of the group, presides over meetings of the group, and conducts the group's business in an orderly fashion. In some organizations, the chairperson is also known as ''president'' (or other title). In others, where a board appoints a president (or other title), the two terms are used for distinct positions. Also, the chairman term may be used in a neutral manner not directly implying the gender of the holder. Terminology Terms for the office and its holder include ''chair'', ''chairperson'', ''chairman'', ''chairwoman'', ''convenor'', ''facilitator'', '' moderator'', ''president'', and ''presiding officer''. The chairperson of a parliamentary chamber is often called the ''speaker''. ''Chair'' has been used to refer to a seat or office of authority ...

Electrical Power Industry
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of posit ...

Croatian Kuna
The kuna is the currency of Croatia, in use since 1994 (sign: kn; code: HRK). It is subdivided into 100 lipa. The kuna is issued by the Croatian National Bank and the coins are minted by the Croatian Mint. The plural form of the word kuna in Croatian can be ''kuna'' or ''kune'' (e.g. ''2 kune'', ''10 kuna'') because of different number declension rules. 2022 will be the final year for the kuna as Croatia will replace it with the euro (€, EUR) on 1 January 2023. All Croatian bank accounts and credit cards will automatically be converted to euros and kuna cash may be exchanged for euros at no charge. The word ''kuna'' means " marten" in Croatian, referring to the historical use of marten pelts as units of value in medieval trading. The word ''lipa'' means " linden (lime) tree", a species that was traditionally planted around marketplaces in Croatia and other lands under Habsburg monarchy rule during the early modern period.

Electricity Generation
Electricity generation is the process of generating electric power from sources of primary energy. For electric utility, utilities in the electric power industry, it is the stage prior to its Electricity delivery, delivery (Electric power transmission, transmission, Electric power distribution, distribution, etc.) to end users or its Grid energy storage, storage (using, for example, the Pumped-storage hydroelectricity, pumped-storage method). Electricity is not freely available in nature, so it must be "produced" (that is, transforming other forms of energy to electricity). Production is carried out in power stations (also called "power plants"). Electricity is most often generated at a power plant by electromechanical electric generator, generators, primarily driven by heat engines fueled by combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Electricity Distribution
Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between and with the use of transformers. ''Primary'' distribution lines carry this medium voltage power to distribution transformers located near the customer's premises. Distribution transformers again lower the voltage to the utilization voltage used by lighting, industrial equipment and household appliances. Often several customers are supplied from one transformer through ''secondary'' distribution lines. Commercial and residential customers are connected to the secondary distribution lines through service drops. Customers demanding a much larger amount of power may be connected directly to the primary distribution level or the subtransmission level. The transition from transmission to distribut ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Jaruga Hydroelectric Power Plant
Jaruga Hydroelectric Power Plant is a hydroelectric power plant on river Krka, located in Šibenik-Knin County, in central Dalmatia, Croatia. The first European hydroelectric power plant was built in Croatia (many people worked together to make this possible). It was put into operation two days after, according to Nikola Tesla's patents, the world's first hydroelectric power plant at Niagara Falls was put into operation. A turbine, two generators (42 Hz, 550 kW) and a transformer made by the Hungarian company Ganz were built under the Skradinski Buk waterfall. The Jaruga is one of the oldest power-generating facilities in the world. Its present location dates back to 1903, when it was moved from the nearby original Jaruga power station built in 1895. History The oldest Jaruga power plant was the first alternating current (AC) power system in Croatia. It was designed to power the street lights in Šibenik, making it the first city in the world with street lights power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adams Power Plant
Adams Power Plant Transformer House in Niagara Falls, New York is a National Historic Landmarked building constructed in 1895. It is the only remaining structure that was part of the historic Edward Dean Adams Power Plant, the first large-scale, alternating current electric generating plant in the world, built in 1895. The building's eponym was Edward Dean Adams, a businessman and entrepreneur in the electrical field. History The Adams power plant followed an 1886 plan by engineer Thomas Evershed to tap the power of Niagara Falls, which involved a "hydraulic canal" and a brick-lined tunnel, when the Niagara Falls Power Company was formed. The Cataract Construction Company, a new company formed to exploit the opportunity, led by president Edward Dean Adams, first formed the International Niagara Commission in 1890 to come up with a plan for harnessing the Falls. The Commission favored electricity, but could not recommend a solution to Cataract. In 1892, George Forbes was hire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niagara Falls
Niagara Falls () is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York. Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than . During peak daytime tourist hours, more than of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate. Niagara Falls is famed for its b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
