Zombini iintambo ze-DC kunye ne-AC zisetyenziselwa ukuhambisa amandla ombane, kodwa ziyahluka kuhlobo lwangoku eziwuphetheyo kunye nezicelo ezithile eziyilelweyo.Kule mpendulo, siza kuphonononga umahluko phakathi kweentambo ze-DC kunye ne-AC, ezigquma imiba efana nohlobo lwangoku, iimpawu zombane, usetyenziso, kunye noqwalaselo lokhuseleko.
Umsinga othe ngqo (DC) ngumsinga wombane oqukuqela kwicala elinye kuphela.Oku kuthetha ukuba i-voltage kunye ne-current ihlala ingatshintshi ngokuhamba kwexesha.I-alternating current (AC), ngakolunye uhlangothi, ngumbane otshintsha indlela ngamaxesha athile, ngokuqhelekileyo kwi-waveform ye-sinusoidal.I-AC yangoku itshintshana phakathi kwe-polarity elungileyo kunye nengalunganga, ebangela ukuba amandla ombane kunye neefom zamaza zangoku zitshintshe ngokuhamba kwexesha.
Umahluko ophambili phakathi kweentambo ze-DC kunye ne-AC luhlobo lwangoku ezilungiselelwe ukuthwala.Iintambo ze-DC zenzelwe ngokukodwa ukuthwala ngoku ngqo, ngelixa iintambo ze-AC zenzelwe ngokukodwa ukuthwala ngokutshintshana ngoku.Ukwahluka kwiindidi zangoku kunokuba nefuthe kuyilo, ukwakhiwa kunye nokusebenza kwezi ntambo.
Omnye umahluko ophambili phakathi kweentambo ze-DC kunye ne-AC yi-insulation kunye ne-conductor esetyenzisiweyo.Iintambo ze-DC zihlala zifuna ukugquma okuthe kratya ukuze zimelane namanqanaba ombane rhoqo kunye notshintsho lwamaza.Zikwafuna iiconductors ezinganyangekiyo ukunciphisa ilahleko yamandla.Iintambo ze-AC,
kwelinye icala, inokusebenzisa i-insulation ebhityileyo ngenxa yobume bexesha lokuhamba ngoku.Basenokuba nezixhobo ezahlukeneyo ze-conductor ukuze baphendule ngesiphumo solusu kunye nezinye i-AC-specific phenomena.Iintambo ze-AC zidla ngokuphawulwa ngamazinga aphezulu ombane xa kuthelekiswa neentambo ze-DC.Oku kungenxa yokuba amandla ombane aphezulu kwiinkqubo ze-AC angaphezulu komndilili wombane, kwaye iintambo kufuneka zikwazi ukumelana nala manqanaba ombane aphezulu.Kwinkqubo ye-DC, i-voltage ihlala ingaguquguquki, ngoko ke uyilo lwekhebula aludingi kwamkela amanqanaba aphezulu ombane.
Ukukhethwa kweentambo ze-DC kunye ne-AC kuxhomekeke kakhulu kwisicelo.iintambo DC ziqhele ukusetyenziswa kwizicelo low-voltage ezifana neenkqubo zeemoto, iipakethi ibhetri, kunye neenkqubo zelanga.Zikwafumaneka rhoqo kwiinkqubo zombane, zonxibelelwano, kunye nekhompyuter ezifuna amandla eDC.Iintambo ze-AC, kwelinye icala, zisetyenziswa kwizicelo eziphezulu zombane ezifana nokuhanjiswa kwamandla kunye nokuhanjiswa, oomatshini boshishino, iintambo zokuhlala kunye nezorhwebo, kunye nezixhobo ezininzi zendlu.
Ngokubhekiselele kwingqwalasela yokhuseleko, iintambo ze-AC zibonisa iingozi ezongezelelweyo xa kuthelekiswa neentambo ze-DC.Ngenxa yokutshintshatshintsha kombane, iintambo ze-AC zinokubangela ukothuka kombane kumaza athile okanye phantsi kweemeko ezithile.Oku kuthetha ukuba kufuneka kuthatyathwe amanyathelo okhuseleko awongezelelweyo xa kusetyenzwa ngeentambo ze-AC, kubandakanywa iindlela ezifanelekileyo zokubeka phantsi komhlaba kunye nobuchule bokugquma.Ngokuchaseneyo, iintambo ze-DC azinabungozi obunxulumene namaza, ngoko ke zithathwa ngokuba zikhuselekile kwezinye izicelo.
Isishwankathelo, umahluko ophambili phakathi kweentambo ze-DC kunye neentambo ze-AC luhlobo lwangoku ezilungiselelwe ukuthwala.Iintambo ze-DC zisetyenziselwa ukuhambisa umsinga othe ngqo, ngelixa iintambo ze-AC zisetyenziselwa ukuhambisa umsinga oguqukayo.Umahluko kuhlobo lwangoku unokuchaphazela uyilo, ukwakhiwa kunye nokusebenza kwezi ntambo, kubandakanywa ukugquma kunye nezixhobo ze-conductor, ukulinganiswa kombane, usetyenziso kunye nokuqwalaselwa kokhuseleko.Ukuqonda ezi ntlukwano kubalulekile ekukhetheni intambo efanelekileyo yenkqubo ethile yombane okanye isicelo.
