Hadaba tusmada yaa iska leh, Tesla iyo Westinghouse, qaab dhismeedka AC-da oo dhameystiran miyuu ku salaysnaa? Marka la eego su'aasha hore, ku qor macnaha guud ee jawaabta. Waxay noqon kartaa 1 ilaa 20 jumladood. Macnaha guud:
Sanadkii 1893 Richard Dean Adams, oo madax ka ahaa shirkada Niagara Falls Cataract Construction Company ayaa raadiyay ra'yiga Tesla ee ku saabsan habka ugu wanaagsan ee lagu gudbin karo korontada ka soo baxda biyo mareenka. Sanado badan waxaa jiray taxane ah soo jeedinno iyo tartanno furan oo ku saabsan sida ugu wanaagsan ee loo isticmaali karo awoodda ay soo saarto dhicitaanka iyadoo nidaamyo badan ay soo jeediyeen dhowr shirkadood oo Mareykan ah iyo Yurub ah oo ay ku jiraan laba waji iyo saddex waji AC, DC danab sare leh, iyo xitaa hawada la cadaadiyay. Adams wuxuu Tesla ka raadiyay macluumaad ku saabsan xaaladaha nidaamyada tartanka. Tesla wuxuu u sheegay Adams in nidaam laba waji leh uu noqon doono kan ugu kalsoonida badan iyo in uu jiro nidaam Westinghouse ah oo lagu shido nalalka laydhka iyadoo la adeegsanayo laba waji oo isbedel ah. Iyada oo ku saleysan talada Tesla iyo bandhigga Westinghouse ee ah inay dhisi karaan nidaam AC oo dhameystiran Bandhigga Columbia, qandaraas lagu dhisayo nidaam laba waji oo AC ah oo ku yaal Niagara Falls ayaa la siiyay Westinghouse Electric. Qandaraas kale oo lagu dhisayo nidaamka qaybinta AC waxaa la siiyay General Electric.
