Electric Motor
An electric motor is an Electric machine, electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a Electromagnetic coil, wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, Inverter (electrical), inverters or electrical generators. Electric motors may be classified by considerations such as power source type, construction, application and type of motion output. They can be powered by AC or DC, be Brushed motor, brushed or Brushless motor, brushless, single-phase, Two-phase electric power, two-p ...

Dynamo
file:DynamoElectricMachinesEndViewPartlySection USP284110.png, "Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator (electric), commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later Electric power conversion, electric-power conversion devices were based, including the electric motor, the Alternating current, alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale Electricity generation, power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a commutator (electric), mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via Solid state (electronics), solid state technology) is effective and usually economical.

Pisa
Pisa ( , or ) is a city and ''comune'' in Tuscany, central Italy, straddling the Arno just before it empties into the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for its leaning tower, the city contains more than twenty other historic churches, several medieval palaces, and bridges across the Arno. Much of the city's architecture was financed from its history as one of the Italian maritime republics. The city is also home to the University of Pisa, which has a history going back to the 12th century, the Scuola Normale Superiore di Pisa, founded by Napoleon in 1810, and its offshoot, the Sant'Anna School of Advanced Studies.Scuola Superiore Sant'Anna di Pisa Information statistics History ...

University Of Pisa
The University of Pisa ( it, Università di Pisa, UniPi), officially founded in 1343, is one of the oldest universities in Europe. History The Origins The University of Pisa was officially founded in 1343, although various scholars place its origins in the 11th century. It is certain, however, that from the middle of the 12th century Pisa had a “Universitas” in the original sense of the word, that is, a group of students who gathered around masters. It was during this period that Leonardo Fibonacci was born and worked. He was one of the greatest mathematicians in history who, through his work, synthesized the spirit and processes of Greek geometry and the tools of Arabic mathematics for the first time in Europe. The papal seal “In Supremae dignitatis”, issued by Pope Clement VI on 3 September 1343, granted the Studium in Pisa the title of Studium Generale with various exclusive privileges, making it universally recognised. In medieval times, the Studium Generale wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Cagliari
The University of Cagliari ( it, Università degli Studi di Cagliari) is a university in Cagliari, Sardinia, Italy. It was founded in 1606 and is organized in 11 faculties. History The ''Studium Generalis Kalaritanum'' was founded in 1606 along the lines of the old Spanish Universities of Salamanca, Valladolid and Lleida, but it begins to operate only after the privilege of King Philip III in 1620. as ''Universidad y Estudio General de Caller en el Reyno de Cerdeña'' (University and Gener Study of Cagliari in the Kingdom of Sardinia). It originally offered Law, Latin, Greek and Hebrew Literature, the Liberal Arts, Medicine, Surgery, Philosophy and Science. When Sardinia passed under the House of Savoy government in the 18th century, the statute of the University was significantly modified, with the expansion of the science faculties and institutes. Designed by the Piedmontese engineer Saverio Belgrano di Famolasco, the new university building was completed at the end of the 1 ...

Augusto Righi
Augusto Righi (27 August 1850 – 8 June 1920) was an Italian physicist and a pioneer in the study of electromagnetism. He was born and died in Bologna. Biography Born in Bologna, Righi was educated in his home town, taught physics at Bologna Technical College between 1873 and 1880, and left to take up the newly established chair of physics at the University of Palermo. He was professor of physics at the University of Padua (1885–89) and later returned to a professorship at the University of Bologna. Righi's early research, conducted in Bologna between 1872 and 1880, was primarily in electrostatics. He invented an induction electrometer, with the help of Dr. Matthew Van Schaeick of the Humboldt University of Berlin, in 1872, capable of detecting and amplifying small electrostatic charges, formulated mathematical descriptions of vibrational motion, and discovered magnetic hysteresis in 1880. Whilst ordinary professor in physics at the University of Palermo, he studied the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People Associated With Electricity
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

19th-century Italian Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule.
