Kwinqaku elandulelayo sele singenisile isahluli sevolthi Ndaye ndachaza ukuba kukho izijikelezi ezininzi kunye neesekethe eziphindaphindayo, ezinje ngezihlandlo okanye imijikelezo yangoku. Kulungile ngoku Siza kunikezela eli galelo kulwahlulelo lwangoku. Njengoko unokuthelekelela kwigama layo, sisekethe enokwahlulahlula ubungakanani okanye ubuninzi besekethe kwimveliso yayo ukuya kumaxabiso asezantsi kunalawo angenisiweyo.
Inyani yile yokuba zonke eziisekethe ezinokuguqula amaxabiso athile ziye kwamanye, nokuba ziwotshi yewotshi, ombane okanye okwangoku njengakule meko, zezona zininzi ziqhelekileyo kwaye ziyasebenza kubungakanani bokusetyenziswa okunokunikwa. Ukongeza, kulula kakhulu ukwakha kunye nexabiso eliphantsi, kwaye inokuba luvavanyo olulungileyo lwabafundi be-elektroniki abafuna ukukhangela umphumo onawo ngee-polym ...
Yintoni umahluli wangoku?
Un ukwahlulahlula ngoku, Njengoko ndiphawulile, yisekethe enokwahlulahlula ubungakanani obukhoyo kwigalelo lazo kwezinye izinto ezincinci kwimveliso yazo. Ukufezekisa oku, zimbalwa izinto ezichasayo ezifunekayo. Njengokuba isahluli sevolthi senziwe ngee-resistors kuthotho, okanye ukuphinda-phinda kwevolthi yayizii-diode ngokudibeneyo, isahlulelo sangoku luthotho lwamanqanaba enziwa ngokuchasene ngokuhambelana.
Khumbula: izixhathisi kuthotho = ukwahlula amandla ombane, izixhathisi ngokungqinelanayo = isahlulelo sangoku
Ke ngoko, ukuba unesahluli sangoku esinezigaba ezibini okanye ezimbini zokumelana ngokudibeneyo, nganye kuzo iya kuba isebenzisa isahlulo sobunzima obupheleleyo. Le yindlela ozahlulahlula ngayo ngoku. Ngamanye amagama, enobuchule ngakumbi, jonga emfanekisweni, ukuba usebenzisa izixhathisi ezibini kuphela, ukuya ukubala ukuba yintoni iziphumo ezikhoyo ngoku, ungohlulahlula ukumelana ne-R1 ngesixa-mali se-R1 + R2 kwaye iziphumo zisiphindaphinde ngamandla apheleleyo (igalelo).
Njengoko ubona, ungabala ukubakho okwangoku kwinqanaba ngalinye ngokwexabiso lezinto ezichasayo. Kwaye ukuba uyafuna, ungongeza amanqanaba okanye izichasi ngokuhambelana kwaye uguqule iifomula zokwazi okwangoku okokugqibela. Khumbula ukuba iiyunithi kufuneka zibe kwi-ohms, kunye nokuqina kwi-amps ... Kulula akunjalo?
Umgaqo osekwe kuwo
Kwaye yintoni Umgaqo-siseko usekwe ukuze wahlule ngoku? Andazi ukuba ufundile i-elektroniki okanye hayi, kodwa xa ufunda uthotho olulula kunye neesekethe ezinqabileyo zokuxhathisa, uxelelwa kwiincwadana kunye neencwadi zokufunda ukuba xa izinto ezichasayo zibekwa ngokudibeneyo izinto zangoku zahlulwe ngeendlela ezininzi.
Ukuba uyakhumbula, ngothotho oluchasayo ombane okanye ombane asasazwa phakathi kwabo (isahluli sevolthi), kodwa amandla okwangoku ahamba kuwo ayafana nalawo anikiweyo. Ngelixa kwi resistors ngaxeshanye ombane ogqitha nganye nganye iyafana, kuba iziphelo zazo zixhunyiwe ngqo kumgca wokubonelela ophambili. Kwelinye icala, xa uthetha ngobunzulu bezinto ezifanayo, ii-amps zihanjiswa phakathi kwazo kuba ayijikelezi kwindlela enye njengakolu chungechunge.
Ufumana njani isahlulelo sangoku
Ngaba ukhe wayibona loo nto ukwenza isahluli somsinga Kufuneka ubenazo ezinye izinto ezichasayo, wenze ubalo oluyimfuneko njengoko ndibonisile kwicandelo elidlulileyo kwaye uye kudlala ngamanqanaba kunye namaxabiso ezinto ezichasayo ukuze ufumane isiphumo osifunayo. Inyani yile yokuba ilula, andinanto ingako yokuthetha ...
Into ekufuneka uyithathele ingqalelo uyisebenzisa, umzekelo, potentiometer njengoko senze ngokwahlulahlula amandla ombane. Ngale ndlela unokuhlengahlengisa amaxabiso kwaye ube nakho ukuzama imultimeter ukubona ukuba umahluko ekuchaseni uchaphazela njani ubungqongqo. Kungumsebenzi osebenzayo wokufundisa.
Y inqaku lokugqibela, Ukuba uyakhumbula xa sasibona isahluli sevolthi, ndathi impazamo eqhelekileyo yayikukucinga ukuba ukuba sibhangqa izinto ezininzi ngokuhambelana neziphumo zazo, ngekhe sibe nombane ofanayo kwaphela. Isizathu? Khumbula ukuba ukuxhathisa kwezinto nganye kuchaphazela i-voltage kunye nokuqina, enyanisweni, isahlulelo sangoku sisekwe kuloo migaqo ...
