Electrotechnica

Le **electrotechnica** es un specialitate del ingenieria que studia e recerca le application del electricitate, electronica e electromagnetismo. 

Le ingenieria electric non include le ingenieria electronic in tote le mundo, con exception del SUA ubi pote on pote includer lo. Le distinction es que le ingenieria electric es considerate specialisate in le grande systemas como transmission de energia electric e controlo de motor, ma le **ingenieria electronic** es specialisate in le systemas electronic a micre scala que pote includer computatores e circuitos integrate.

## Historia
Le electricitate ha essite un subjecto de interesse scientific depost le experimentationes scientific de Alessandro Volta in 1775 sur le electrophoro, un apparato que produce un cargamento de electricitate static, e depost 1800 quando Volta ha disveloppate le pila voltaic, un precursor del batteria electric.

In le seculo 19 le recerca in le subjecto se intensificava. Le disveloppamentos notabile in le seculo 19 include le labor de Georg Ohm, qui in 1827 ha discoperite le relation quantitative inter le currente electric e differentia de potential in un conductor, Michael Faraday, le discoperitor del induction electromagnetic in 1831, e James Clerk Maxwell, qui in 1873 ha publicate un theoria unificate inter le electricitate e magnetismo in *Electricity and Magnetism*.

 
Le Universitate de Technologia de Darmstadt fundava le prime facultate de ingenieria electric in 1882. Antea, le electricitate ha essite considerate un sub-specialitate del physica.  

In 1882, Edison ha cliccate le button del prime rete electric a grande scala que forniva 110 volts DC (currente directe) a 59 clientes in Manhattan. In 1887, Nikola Tesla submitteva un numero de patentes de distribution de currente como AC (currente alternante). AC ha reimplaciate DC pro le generation e distribution de energia electric.

Le labor de Tesla in motor de induction e systema polyphase ha influentiate le specialitate pro le futuro, e Edison ha laborate in telegraphia e le compania de ille ha devenite General Electric. 

### Disveloppamentos moderne
; Emergentia de radio e electronica
In le experimentos classic de frequentia ultra-alte UHF de 1888, Heinrich Hertz ha transmittite e ha detegite undas radio usante equipamento electric. In 1895, Nikola Tesla ha facite transmissiones a un distantia de 80.4 km. 

## Education
Ingenieros electric ha un grado academic con un major in ingenieria electric. Le longitude de studios es 5 annos.
