I-resistor yicandelo lombane elisebenzayo ukudala ukuchasana nokuhamba kwamandla ombane. Phantse kuzo zonke iinethiwekhi zombane kunye neesekethe ze-elektroniki zinokufumaneka. Ukuxhathisa kulinganiswa ngee-ohms. I-ohm luxhathiso olwenzeka xa i-current ye-ampere enye idlula kwi-resistor kunye ne-volt enye yehla kwiitheminali zayo. Ixesha langoku lilingana nombane onqumla kwiziphelo zetheminali. Lo mlinganiselo umelwe nguUmthetho ka-Ohm:

I-resistors isetyenziselwa iinjongo ezininzi. Imizekelo embalwa ibandakanya i-delimit current yombane, ulwahlulo lombane, ukuveliswa kobushushu, ukufanisa kunye nokulayisha iisekethe, ukuzuzwa kokulawula, kunye nokulungisa amaxesha azinzileyo. Zifumaneka ngokurhweba kunye namaxabiso okumelana noluhlu olungaphezulu kwee-odolo ezilithoba zobukhulu. Zingasetyenziswa njengeziqhoboshi zombane zokuchitha amandla e-kinetic koololiwe, okanye zibe zincinci kune-square millimeter yombane.

Amaxabiso axhathisayo (Amaxabiso akhethwayo)
Ngeminyaka yee-1950 ukwanda kwemveliso yezinto ezixhathisayo kwadala imfuneko yomgangatho wokuxhathisa okusemgangathweni. Uluhlu lwamaxabiso okumelana lubekwe emgangathweni kunye nokubizwa ngokuba ngamaxabiso akhethiweyo. Amaxabiso akhethwayo achazwa kwi-E-series. Kuluhlu lwe-E, ixabiso ngalinye liyipesenti ethile ephezulu kuneyangaphambili. Kukho iindidi ezahlukeneyo ze-E zokunyamezelana okwahlukileyo.

Izicelo zokuchasa
Kukho umahluko omkhulu kwimimandla yezicelo zokumelana; ukusuka kumacandelo achanekileyo kwi-elektroniki yedijithali, ukuya kwizixhobo zokulinganisa ubungakanani bomzimba. Kwesi sahluko izicelo ezininzi ezidumileyo zidweliswe.

Resistors kuthotho kunye parallel
Kwiisekethe ze-elektroniki, izixhasi zihlala ziqhagamshelwe kuthotho okanye ngokuhambelanayo. Umyili wesekethe unokuthi umzekelo adibanise izichasi ezininzi kunye namaxabiso asemgangathweni (E-series) ukufikelela kwixabiso elithile lokumelana. Kuluhlu loxhulumaniso, yangoku ngokusebenzisa resistor nganye iyafana kunye noxhathiso elinganayo ilingana isixa isichasi ngamnye. Ukudibanisa okuhambelanayo, i-voltage ngokusebenzisa i-resistor nganye iyafana, kwaye i-inverse ye-resistance resistance ilingana ne-sum of the values ​​of inverse for all resistors parallel. Kumanqaku aphikisayo ngokuhambelana kunye nochungechunge inkcazo ecacileyo yemizekelo yokubala inikwe. Ukusombulula iinethiwekhi ezinzima ngakumbi, imithetho yesekethe yaseKirchhoff ingasetyenziswa.

Ukulinganisa umsinga wombane (i-shunt resistor)
Umbane wangoku unokubalwa ngokulinganisa ukuhla kwamandla ombane phezu kwe-resistor echanekileyo kunye nokumelana okwaziwayo, okudibaniswe kwichungechunge kunye nesekethe. Ikhoyo ngoku ibalwa ngokusebenzisa umthetho we-Ohm. Oku kubizwa ngokuba yi-ammeter okanye i-shunt resistor. Ngokuqhelekileyo oku kuchanekileyo okuphezulu kwe-mangan resistor enexabiso eliphantsi lokumelana.

I-Resistors kwii-LEDs
Izibane ze-LED zidinga umsinga othile ukuze usebenze. Umsinga ophantsi kakhulu awuyi kukhanyisa i-LED, ngelixa umsinga ophezulu kakhulu unokutshisa isixhobo. Ke ngoko, bahlala bedityaniswa ngokulandelelana kunye ne-resistors. Ezi zibizwa ngokuba yi-ballast resistors kwaye zilawula ngokungahambi kakuhle okwangoku kwisekethe.

Isixhasi senjini yokuvuthela
Ezimotweni isixokelelwano sokuphefumla komoya siqhutywa yifeni eqhutywa yinjini yokuvuthela. I-resistor ekhethekileyo isetyenziselwa ukulawula isantya se-fan. Oku kubizwa ngokuba sisixhathisi senjini yokuvuthela. Uyilo olwahlukileyo luyasetyenziswa. Olunye uyilo luluhlu lwezixhasi ezahlukeneyo zobungakanani be-wirewound kwisantya somlandeli ngamnye. Olunye uyilo lubandakanya isekethe edibeneyo ngokupheleleyo kwibhodi yesekethe eprintiweyo.
