Umphengululi yinto yombane obonakalayo ukwenza ukumelana nokuhamba kombane. Phantse zonke iinethiwekhi zombane kunye nesekethe ezikwi-elektroniki ezinokufunyanwa. Ukuchasana kulinganiswa kwi-Ohms. I-OHM kukuchasana okwenzekayo xa kwangoku i-AMPER ye-AMPERE igqitha ngokurhoxa nge-volt enye yehla. Okwangoku ihambelana ne-voltage kuyo yonke imiphetho. Lo mlinganiso umelweUmthetho ka-Ohm:

Abaqeqesha basetyenziswa ngeenjongo ezininzi. Imizekelo embalwa iquka ukuthambisa ngombane, isahlulo se-voltage, isizukulwana somtshilo, ukudibanisa nokulayisha isekethe, ukulawula, kunye nokulungisa ixesha hlala ixesha. Zifumaneka ngorhwebo ngeenqobo zokuchasana nokungaphezulu kwee-odolo ezingaphezulu kwesithoba. Zingasetyenziselwa njengeebhuleki zombane zokuchitha amandla e-kinetic kumanzi avela kuzo zoololiwe, okanye zincinci kunemilimi ye-millimitha ye-elektroniki.

Amaxabiso e-resistor (amaxabiso achongiweyo)
Kwiminyaka yee-1950s Ukuveliswa okwandisiweyo kwabaqeqeshayo kwadala imfuneko yokuchasana nemilinganiselo yokuchasana. Uluhlu lwexabiso lokuxhathisa lubekwe emgangathweni kunye namanani afunwayo. Amaxabiso akhethwayo achazwa kwi-E-uthotho. Kwi-e-uthotho, ixabiso ngalinye yipesenti ethile ephezulu kunangaphambili. Uchungechunge olwahlukeneyo lwe-EE-lukhona ukudilizwa okwahlukileyo.

Izicelo zoncedo
Kukho umahluko omkhulu kwimihlaba yezicelo zabaqeqeshayo; Ukusuka kwizinto ezichanekileyo kwi-elektroniki yedijithali, kude kube zizixhobo zokulinganisa. Kule minyaka izicelo ezininzi ezithandwayo zidwelisiwe.

Abaqengqelelweyo ngothotho kunye nokufana
Kwisekethe ze-elektroniki, abaqeqesha bahlala bedibene kakhulu kuthotho okanye ngokuhambelana. Umyili wesiphaluka usenokuba umzekelo udibanisa abaqeqeshwayo ngexabiso eliqhelekileyo (e-uthotho) ukufikelela kwixabiso elithile lokuchasana. Uqhagamshelo lwengcenti lwengcenti, okwangoku ngokusebenzisa umthi-mali nganye iyafana kwaye ukunganyangeki okulinganayo kuyalingana nesiphumo sabaqeshwa abathile. Unxibelelwano olufanayo, ivolthi yokurhoxiswa komvuzo ngamnye iyafana, kwaye i-interrenting yokunyangeka ngokulinganayo ilingana nexabiso elingafaniyo kubo bonke ababandezeli. Kumanqaku abaqeqeshayo ngokuhambelana nenkcazo eneenkcukacha yokuBala inikiwe. Ukusombulula ngakumbi kwiinethiwekhi ezintsonkothileyo, imithetho yesekethe i-Kirchhoff inokusetyenziswa.

Ukulinganisa umbane okhoyo (Shunt)
Okwangoku kombane zinokubalwa ngokulinganisa i-voltage yehla ngaphezulu komvuzo ochanekileyo, onxulumene nothotho lwesekethe. Okwangoku ibalwa ngokusebenzisa umthetho we-Ohm. Eli libizwa ngokuba yi-ammeter okanye i-runt yokurhoxa. Ngokwesiqhelo lo ngumthombo ophezulu we-manganin ochanekileyo ngexabiso elingaphantsi lokuchasana.

Abaqeqeshi bee-LED
Izibane ze-LED zifuna okwangoku ukusebenza. Okwenziweyo kakhulu okwangoku awuyi kukhanyisa i-LED, ngelixa i-high kakhulu yangoku inokutshisa isixhobo. Ke ngoko, bahlala benxibelelana nothotho lwabaqeqeshi. Oku kubizwa ngokuba ngabaphengululi be-ballast kwaye balawula ngokugqithisileyo kwisekethe.

I-bloer motor
Kwiimoto Inkqubo yomoya ophumeleleyo yenziwa ngu-fan oqhutywa yimoto evuthuzayo. Isicelo esikhethekileyo sisetyenziselwa ukulawula isantya se fan. Oku kubizwa ngokuba ngumthi-mbala wemoto. Uyilo olwahlukileyo luyasetyenziswa. Uyilo olunye luthotho lwe-wirewound eyahlukileyo ye-Wrewound yesantya ngasinye se fan. Olu luyilo lubandakanya isekethe elihlanganisiweyo kwiBhodi yeSiphako eprintiweyo.
