Dị ka anyị niile maara, e nwere ike kewaa generators DC generators na AC generators. Ka ọ dị ugbu a, a na-eji alternator eme ihe n'ọtụtụ ebe, otu ahụ ka a na-ejikwa hydro generator. Mana n'afọ ndị mbụ, ndị na-emepụta DC na-eji ahịa ahụ dum, yabụ kedu ka ndị na-emepụta AC si nọrọ n'ahịa ahụ? Kedu njikọ dị n'etiti igwe na-emepụta mmiri ebe a? Nke a bụ maka agha AC na DC na 5000hp hydro generator nke Adams power station na Niagara Falls.
Tupu iwebata Niagara Falls hydro generator, anyị ga-amalite na agha AC / DC dị oke mkpa na akụkọ ihe mere eme nke ọkụ eletrik.
Edison bụ onye America na-emepụta ihe ama ama. A mụrụ ya na ịda ogbenye, ọ nweghịkwa agụmakwụkwọ ụlọ akwụkwọ. Otú ọ dị, ọ nwetara ihe fọrọ nke nta ka ọ bụrụ 1300 chepụta patent na ndụ ya site na ịdabere na ọgụgụ isi ya pụrụ iche na mmụọ mgba onwe ya. N'October 21, 1879, o tinyere akwụkwọ maka ịmepụta patent nke carbon filament incandescent oriọna (Mba 22898); N'afọ 1882, ọ tọrọ ntọala Edison ụlọ ọrụ ọkụ eletrik iji mepụta oriọna ọkụ na ndị na-emepụta DC ha. N'otu afọ ahụ, o wuru ụlọ ọrụ ọkụ ọkụ mbụ buru ibu na New York. Ọ rere ihe karịrị 200000 bulbs n'ime afọ atọ na monopolized dum ahịa. Ndị na-emepụta ihe DC nke Edison na-erekwa nke ọma na kọntinent America.
N'afọ 1885, mgbe Edison nọ na ọnụ ọgụgụ ya, American steinhouse hụrụ nke ọma usoro ọkụ ọkụ AC a mụrụ ọhụrụ. N'afọ 1885, Westinghouse zụtara patent na sistemụ ọkụ AC na transformer etinyere site na gaulard na Gibbs na United States na February 6, 1884 (US Patent No. n0.297924). Na 1886, Westinghouse na Stanley (W. Stanley, 1856-1927) nwere ihe ịga nke ọma n'ịkwalite otu-phase AC ka 3000V na a transformer na Great Barrington, Massachusetts, USA, na-ebunye 4000ft, wee belata voltaji na 500V. N’oge na-adịghị anya, Westinghouse mere ma ree ọtụtụ sistemụ ọkụ AC. Na 1888, Westinghouse zụtara patent nke Tesla, onye nwere ọgụgụ isi eletriki, na moto AC, wee were Tesla were rụọ ọrụ na Westinghouse. O meela n'ịzụlite moto AC na ịkwalite ngwa nke moto AC, wee nweta ihe ịga nke ọma. Mmeri nke Westinghouse na-aga n'ihu n'ịzụlite mgbanwe mgbanwe ugbu a dọtara anyaụfụ nke Edison a na-apụghị imeri emeri na ndị ọzọ. Edison, HP brown na ndị ọzọ bipụtara isiokwu na akwụkwọ akụkọ na akwụkwọ akụkọ, were ohere nke ọha na eze na-atụ egwu ọkụ eletrik n'oge ahụ, achọghị ikwusa ozi ọma ihe ize ndụ nke alternating ugbu a, na-azọrọ na "niile ndụ nso alternating ugbu a ndu enweghị ike ịlanarị" na ọ dịghị ndụ kere nwere ike ịdị ndụ n'ihe ize ndụ nke conductors na-ebu uzo ozo ugbu a N'akwụkwọ ya, ọ wakporo ojiji nke AC na mgbalị nke straancy. Na-eche mwakpo nke Edison na ndị ọzọ ihu, Westinghouse na ndị ọzọ dekwara akụkọ iji chebe AC. N'ihi arụmụka ahụ, akụkụ AC ji nwayọọ nwayọọ merie. Akụkụ DC adịghị njikere ịla n'iyi, HP Brown (mgbe ọ bụ onye inyeaka ụlọ nyocha nke Edison) Ọ gbakwara ume ma kwadoo ọgbakọ steeti ka ha nyefee iwu maka igbu ntaramahụhụ ọnwụ site na electrocution, na May 1889, ọ zụtara ndị ọzọ atọ nke Westinghouse mepụtara wee ree ha n'ụlọ mkpọrọ dị ka ike na-enye oche maka oche eletrik. N'anya ọtụtụ ndị, alternating ebili mmiri bụ otu ihe ahụ Chineke nke ọnwụ. N'otu oge ahụ, ndị Congress Congress n'akụkụ Edison kere echiche ọha na eze: "Oche eletrik bụ ihe akaebe na mgbanwe nke ugbu a na-eme ka ndị mmadụ dị mfe ịnwụ. Na nzaghachi, Westinghouse nwere tit for tat press ogbako. akụkụ nwara igbu alternating current n'ụzọ iwu.
N'oge opupu ihe ubi nke 890, ụfọdụ ndị omeiwu na Virginia tụpụtara atụmatụ maka "maka mgbochi nke ihe ize ndụ site na ọkụ eletrik" Ná mmalite nke April, nzuko omeiwu hibere ndị juri ka ha nwee ikpe. Edison na Morton, onye isi njikwa nke ụlọ ọrụ ahụ, na LB Stillwell, injinia nke Westinghouse (1863-1941) na onye ọka iwu nchekwa h. Ndị Livaị gara ikpe ahụ. Ọbịbịa nke Edison a ma ama gbochiri ụlọ omeiwu ahụ. Edison kwuru n'ụzọ na-emetụ n'ahụ n'anụ ahụ, sị: " kpọmkwem ugbu a dị ka "osimiri nke na-eru n'udo n'oké osimiri ", na mgbanwe nke ugbu a dị ka" iyi ugwu na-asọpụta n'ike n'ike "(mmiri na-agba ọsọ n'ike n'ike n'elu ugwu)" Morton gbalịkwara ike ya ịwakpo AC, mana akaebe ha enweghị isi na enweghị nkwenye, nke mere ka ndị na-ege ntị daa na ndị na-ekpe ikpe. Ndị akaebe sitere na Westinghouse na ọtụtụ ụlọ ọrụ ọkụ eletrik gbaghaara arụmụka ahụ na AC dị oke egwu na asụsụ teknụzụ dị nkenke na nke doro anya yana omume ọkụ eletrik 3000V ha ejirila ọtụtụ ebe. N'ikpeazụ, ndị juri ahụ mere mkpebi mgbe arụmụka gasịrị ka Virginia, Ohio na steeti ndị ọzọ gọnarịrị mkpesa ndị yiri ya. Kemgbe ahụ, AC ji nwayọọ nwayọọ nabata ndị mmadụ, Westinghouse nwere aha na-eto eto na agha nke nkwurịta okwu (dịka ọmụmaatụ, na 1893, ọ nakweere nkwekọrịta iwu maka 250000 bulbs na Chicago Fair) Edison Electric Light Company, bụ nke e meriri n'agha AC / DC, bụ onye a na-asọpụrụ na enweghị ike. Ọ ga-ejikọta ya na Thomson Houston ụlọ ọrụ na 1892 iji guzobe ụlọ ọrụ eletriki n'ozuzu (GE) Ozugbo e guzobere ụlọ ọrụ ahụ, ọ gbahapụrụ echiche Edison nke imegide mmepe nke AC akụrụngwa, ketara ọrụ nke n'ichepụta AC akụrụngwa nke mbụ Thomson Houston ụlọ ọrụ, na ike na-akwalite mmepe nke AC akụrụngwa.
Ihe dị n'elu bụ agha dị mkpa n'etiti AC na DC na akụkọ ihe mere eme nke mmepe moto. Esemokwu ahụ mechara kwubie na mmerụ ahụ nke AC adịghị njọ dịka ndị na-akwado DC kwuru. Mgbe mkpebi a gasịrị, alternator malitere ịmalite mmiri nke mmepe, àgwà ya na uru ya malitere ịghọta ma jiri nwayọọ nwayọọ nabata ndị mmadụ. Nke a bụkwa mgbe e mesịrị na Niagara Falls N'ime ndị na-emepụta mmiri na ọdụ ụgbọ mmiri, onye ọzọ bụ ihe na-emeri ọzọ.
