Yintoni na uqhagamshelo serial?

uqhagamshelo Series - yinto ezimbaxa apho izinto ezidityaniswe kuphela kwelinye icala. Ulandelelwano ungachazwa ukuba ayibandakanyi nayiphi eyayizalwa.

Uxhulumaniso series of parallel ungachazwa ukuba yenziwe ngendlela uxhulumaniso ngaxeshanye, ekufuneka libe yindawo ubuncinane ezimbini.

Resistors - ezi zinto yenkcaso sokwenziwa. Bona zisetyenziswa elektroniki njengoko umthwalo owongezelelweyo ukunciphisa ombane okanye yesekethe yangoku. kwenziwa njani oku?

Ukuba kuyimfuneko ukunciphisa ngoku, oko kwenziwa uqhagamshelwano uthotho resistors. Kulo mzekelo, luvukelo yangoku nganye iyafana kwaye umahluko ezinokubakho wahlukile. Kufuneka kuqatshelwe ukuba umahluko ezinokubakho - oko kukuthi, ubuninzi idrophu ombane, kuxhomekeke kweelana le resistor.

Umzekelo, ejikeleza kunye lombane 220 V na ukumelana Ikhoyili 1 Ohm. Ukuba omnye emiphethweni yayo yomibini ukuba angenise kwisigaba, kwaye eyesibini - zero, enyanisweni apho kuya kubakho short circuit, ukuze 1 Ohm - yinto encinane kakhulu. kuya kubakho ngoku omkhulu, Ikhoyili litshise, wayibhula yenethiwekhi. Ukuba lale kuthotho ukubeka resistors ezimbini ohms 500, wesiphaluka elifutshane akunjalo, kwaye coil iza kusebenza ngendlela ekumele.

Xa uxhulumaniso engumzekelo nganye imisinga zesebe ziya kwahluka; kodwa ombane kuya kuba njalo. Ngoko ke, ixabiso yangoku inxalenye nganye kuxhomekeke uxhathiso kwale nxalenye. Esi sikimu isetyenziselwa ukunyusa nethontsi ombane. Umzekelo, kweelana Ikhoyili yenzelwe 50 B. Ukwenza lo msebenzi ku-220, kufuneka enxuseneyo ukunikezela ukuxhathisa efanelekileyo. On iya kudala idrophu ombane, kwaye coil akayi ukuvutha.

Ngenxa yoko, uqhagamshelo enxuseneyo serial asetyenziswa kwiimeko ezizodwa usebenza ngokuvumelana nomthetho Ohm kaThixo.

Ukuba wenziwe uqhagamshelo uthotho le-LED, kuyimfuneko ukuba ukukhumbula ukuba kukho ukusilela ubuncinane omnye wabo uya ukucima yonke chain. Njengoko sele kukhankanyiwe, lowo yangoku endaweni iintlawulo breakage flow yaphinde le sekethe yaphulwe. Xa uqhagamshele ngaxeshanye, kwaye ayinamsebenzi apho LED sinesiphene, enye iya kuqhubeka, kunokutshiseka.

Ukuba ukuxhathisa series ngokusebenzisa enye amahlelo resistors, imali iyonke nto ilingana udibaniso ukuxhathisa ngenani olupheleleyo lweziqalelo.

Ukuba amaxabiso resistor yahlukile, ngoko luvukelo iyonke ilingana umdibaniso resistances isiqalelo ngasinye.

Xa uqhagamshele kwi ukubala ngaxeshanye kuqhutywa noko ngolunye uhlobo. Umzekelo, kukho nomxokelelwane ezintathu mahlelo resistances R1, R2, R3. Ukuze ufumane uxhathiso lilonke beesekethe ngokunxulumene ngaxeshanye, kuyimfuneko ukubala inani reciprocals yexabiso yala mahlelo, ngamanye isongiwe yodwa amaqhezu amathathu 1 / R1 + 1 / R2 + 1 / R3. Amaqhezu bancipha zifana - kwaye ibalwa umphumo. Iqhezu eliphuma omfusa kwaye igqalwa ixabiso lokugqibela.

Ukuze pick up umlo nayiphi wesekethe, ukuba kuyimfuneko ukwenza izibalo ngokuchanekileyo. Ezinye iingcali kulanda resistors ngokukwenza. Noko ke, kule meko, ubuncinane kalukhuni ukuba zeziphi amaxabiso resistor inokuba kangangoko.
