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 atshintshileyo.Zifumaneka ngokurhweba ngemilinganiselo yokumelana noluhlu olungaphezulu kwee-odolo ezilithoba zobukhulu.Zingasetyenziselwa njengeziqhoboshi zombane zokuchitha amandla e-kinetic koololiwe, okanye zibe zincinci kune-square millimeter ye-electronics.

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.Kudibaniso lwechungechunge, ikhoyo ngoku nge-resistor nganye iyafana kwaye ukuchasana okulinganayo kuyalingana nenani labachasi ngabanye.Kudibaniso oluhambelanayo, i-voltage ngokusebenzisa i-resistor nganye iyafana, kwaye i-inverse ye-resistance resistance ilingana ne-sum of the values ​​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 isiphaluka esihlanganiswe ngokupheleleyo kwibhodi yesekethe eprintiweyo.
