AC amandla. DC ne AC yangoku

Nawuphi na umntu okhethe ukusebenza ubunjineli yombane njengoko umsebenzi, kufuneka baqonde kakuhle kakhulu into imithombo yobonelelo, kwakunye neempawu zawo kunye nomahluko. Enyanisweni, akukho lula, njengokuba siza kubonisa kweli nqaku.

Kunzima ukucinga ukuba khangela njani ihlabathi mihla shwaka ukusuka yakhe yamandla ombane kunye zombane ezinxulumeneyo. Mhlawumbi, abantu kuqhubeka ukusebenzisa iinjini zomphunga izihlunu ngamandla kwezilwanyana kunye nabazalwana babo. Umntu athi ngqo kuqala wafumanisa amandla ombane: umzekelo, spinners e Syria bamandulo impahla yegolide evuthiweyo magnetized (umbane), uAristotle wazama ukuhlola amathuba ray yombane, kodwa kuthekani ngengozi umbane sele kwaziwa ukususela ekuqaleni kwehlabathi (akukho Shono abanye abantu babenqula yakhe).

Umbane yi kwiintlobo ezimbini - AC ne DC. Lo mahluko kungenxa indlela yayo ukulungiselela. Ngako oko, i-AC wamandla inika yangoku uhlobo lokuqala kunye rhoqo - yesibini. Hi ndlela leyi, apha ukwahlulwa ibe "yokuqala - yesibini" phantsi kwemiqathango ethile. Electrical Engineering, isetyenziswa njenge unikezelo amandla AC ne DC. Makhe ukukhumbula theory ethile.

Nayiphi ombane imele intshukumo amasuntswana ebizwayo ngqo ecaleni izinto conductive yomkhosi EMF electromotive. amanyathelo lwangaphandle ngokutsho kwezinye electron kwi zisuke zangaphandle athom, namandla ngokwaneleyo ukoyisa nokutsala isiqalo. Ngenxa yoko, kukho mahala abathwali kwentlawulo - electron kunye ion. Ngokutsho komthetho zolondolozo amandla, ngenkqubo amasuntswana recombination zendalo ukusuka athom ezingqonge kumaziko ngekroba. Ngaphandle Isakhiwo ingxelo lwangaphandle zokufunda kwakhona. Noko ke, ukuba umqhubi oludityaniswe ngumthombo amandla electromotive, intsimi eyenziweyo awaye ukuya recombination kwicala lasekunene - umsinga wombane. Enyanisweni AC imele generator EMF kumda wesangqa kabani orientation kuyahlukana ngamaxesha emuva. Ngenxa yoko igama "bume". AC umbane kwiimeko ezininzi amelwe omlinganiselo - ezivelisa izityalo amandla mihla bathela ngqo alternating current. Bona zithembekile ngakumbi isebenza kunye lula ukuba agcine, ngaphezu imodeli mbuthi for DC. Le mithombo amandla imizobo AC zidla elityunjwe onale igagasi ngaphakathi. Le wave - umfanekiso yokomfuziselo ibe sengozini sine.

AC umthombo uvelisa intshukumo ye amasuntswana hayi kuphela ukutshintsha ulwalathiso, kodwa "ezidadayo" Ixabiso amandla. sinusoid okupheleleyo ibonisa ukuba ngamaxesha ixabiso edlula zero.

On amandla eyahlukileyo ngokupheleleyo umgaqo esekelwe DC. Zakha umqhubi intsimi rhoqo zombane kwicala yokutshata intshukumo bengabaveleli yamasuntswana zemiyalelo. Kucingwa ukuba ngoku aqukuqela ukusuka HIV qha okubi (ukusuka elihle negative). Enyanisweni, electron sihambe ngendlela eyahlukileyo - ukusuka thabatha dibanisa. Ekubeni ophethe electron enye alinasiphumelo, iosiphelo oluthi "thabatha" ibonisa obugqithisileyo amasuntswana (kungoko intlawulo iyonke). Ngokusekelwe yokuba amasuntswana ngokufanayo oppositely icala umdla omnye komnye, kube nzima ukuba baqashele ukuba electron ukuhamba ngapha umqhubi ukusuka 'thabatha' a 'dibanisa'. Avumelekile utshintsho yokufakelwa ixabiso yangoku - yale yangoku aliyeki ukuba uhlale ngonaphakade. Kukho izisombululo ezininzi ezahlukeneyo ukuguqula yangoku ngqo nokuxuba (sine wave ezivelisa) and vice versa (rectifiers, kwo).
