Transformer
A transformer is a static device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding. This varying magnetic field induces a varying electromotive force (EMF) or "voltage" in the secondary winding. This effect is called mutual induction.
If a load is connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp), and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np) as follows:
By appropriate selection of the ratio of turns, a transformer thus allows an alternating current (AC) voltage to be "stepped up" by making Ns greater than Np, or "stepped down" by making Ns less than Np.

Nikola Tesla
Nikola Tesla (Serbian: Никола Тесла; 10 July 1856 – 7 January 1943) was an inventor, mechanical engineer, and electrical engineer. He was an important contributor to the birth of commercial electricity, and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor. This work helped usher in the Second Industrial Revolution.
Born an ethnic Serb in the village of Smiljan (now part of Gospić), in the Croatian Military Frontier of the Austrian Empire (modern-day Croatia), Tesla was a subject of the Austrian Empire by birth and later became an American citizen. Because of his 1894 demonstration of wireless communication through radio and as the eventual victor in the "War of Currents", he was widely respected as one of the greatest electrical engineers who worked in America. He pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. In the United States during this time, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture. Tesla demonstrated wireless energy transfer to power electronic devices as early as 1893, and aspired to intercontinental wireless transmission of industrial power in his unfinished Wardenclyffe Tower project.
Because of his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist by many late in his life. Tesla died with little money at the age of 86 in a hotel suite in New York City.
¿Cuando nacio Nikola Tesla?
Nació el 10 de Julio de 1856.
¿Cual fue el lugar de nacimiento de Nicola?
Tesla nacio en Croacia en la poblacion de Smiljan ahora conocido como Gospić.
¿En materia de electricidad cuales fueron sus aportes más importantes en materia de electricidad?
Entre sus multiples trabajos sobre todo en el campo del electromagnetismo, Tesla demostró que podía transmitirse energía eléctrica en forma de corriente alterna y en sistemas polifásicos loque contibuyo ampliamente a la electricidad moderna sobre todo a la electricidad comercial. Además contribuyo a la creación del motor eléctrico dando gran impulso a la revolución industrial.
¿A qué edad y donde murió Nikola Tesla?
Tesla murió a la edad de 86 años en la suite de un hotel de nueva york en enero del año de 1943.
