Ukumelana kwangaphakathi nencazelo yalo ngokomzimba

Ngamunye umthombo zamanje inezidingo ukumelana layo langaphakathi. Isifunda kagesi - ngesimiso somshini esivalekile ne abathengi lapho voltage sisetshenziswa. nentaba ngamunye has ukumelana zangaphakathi nezangaphandle.

Ukumelana Lwangaphandle lonke wesifunda ibizwa ngokuthi amakhasimende kanye babashayeli, kanye ukumelana yangaphakathi livela umthombo.

Uma umthombo lwamanje umshini kagesi, bese impedance layo langaphakathi sehlukaniswe esebenzayo, exhasa futhi capacitive. Umqhubi asebenzayo incike ubude balo ukujiya, kanye impahla kusukela lapho umqhubi, futhi isimo salo. Inductive incike inductance ikhoyili (ezidlula yayo EMF) kanye capacitance elakhiwe ekujikiseni we Windings. It mncane impela. Uma umthombo ibhethri ezivamile, ukumelana ngenxa electrolyte yaso nayo wadala.

Yamanje - esivusa iqondiswe izinhlayiya kanye ukumelana - ukudala isithiyo ukuhamba kwayo. izithiyo ezinjalo nazo electrolyte kanye amapuleti phambili amabhethri, ngamafuphi, nomaphi lapho kukhona samanje.

Ngenxa yokuthi kukhona ukumelana kwangaphakathi umthombo, akunakwenzeka ukuba bakholelwe ukuthi amaphaphu iketango - lena umthombo okuphelele amandla electromotive. Yiqiniso, yokwehla kwamandla emthonjeni kungenziwa indiva, kodwa kuphela uma azinakwa.

Uma supply chain kukhona imisinga okusezingeni eliphezulu, voltage esibulalayo ayikwazi kubhekwa amandla kweqiniso electromotive. Lamanje kumthombo - kuwuphawu yokwehla kwamandla kuwo. Kulokhu, umthetho Kirchhoff, othi kweqiniso EMF uchungechunge - yinani lika voltage lehla kuzo zonke izindawo ezinhle, kuhlanganise nalabo emthonjeni. Ifomula kulotshiwe njengoba:

E = ΣU + Iri r

lapho:

E - inani amandla electromotive of wesifunda;
U - voltage iconsi ku izigaba wesifunda;
Ir - zamanje yangaphakathi ezivezwa umthombo;
r - yangaphakathi umthombo impedance.

Ukuze siqonde okushiwo ezingokomzimba ukumelana sangaphakathi umthombo, kufanele kube khona ulwazi oluthile. Ekuqaleni kulinganiswa electromotive umthombo amandla. Lokhu kwenziwa ngokuxhuma i voltmeter ukuba ibhethri, engesiyo ngaphansi komthwalo. Emva kwalokhu, ukumelana encane ixhumeke uchungechunge futhi ammeter isethi. Ngakho, lamanje empeleni iyokwaziwa, kuyilapho kubalulekile futhi ukukala voltage ngaphansi komthwalo.

Ukucacisa amagugu azo zonke kulula ukunquma ukumelana kwangaphakathi. Ukuze wenze lokhu, okokuqala kunqunywa iconsi voltage ibhethri. Ukusebenzisa ifomula

Uri = EU

Thina ukwenza izibalo.

Kulesi ifomula:

Uri - uphonsa yangaphakathi umthombo voltage ukumelana;
E - voltage (amandla electromotive) kulinganiswa emthonjeni ngaphandle umthengi;
U - voltage, kulinganiswa ngqo ukumelana.

Ngakho, ukumelana yangaphakathi ibalwa le ndlela elandelayo:

r = Uri / I

Abanye ochwepheshe indiva lesi silinganiso, ucabangela ukuthi akunakugwenywa ngenxa yenani elincane. Nokho, umkhuba libonisa ukuthi izibalo eziyinkimbinkimbi ukumelana yangaphakathi kuthinte kakhulu umphumela wokugcina.
