I-resistor yinxalenye yombane engasebenziyo ukwenza ukuxhathisa ekuhambeni komsinga wombane. Phantse kuzo zonke iinethiwekhi zombane kunye neesekethe ze-elektroniki zinokufumaneka. Ukuxhathisa kulinganiswa ngee-ohms. I-ohm kukuxhathisa okwenzeka xa umsinga we-ampere enye udlula kwi-resistor ene-volt drop enye kwiiterminal zayo. Umsinga ulingana ne-voltage kwiziphelo zeterminal. Lo mlinganiselo umelwe yiUmthetho ka-Ohm:

Iiresistor zisetyenziselwa iinjongo ezininzi. Imizekelo embalwa ibandakanya umda wamandla ombane, ukwahlulwahlulwa kwevolthi, ukuvelisa ubushushu, ukufanisa nokulayisha iisekethe, ukufumana ulawulo, kunye nee-fix time constants. Zifumaneka kurhwebo kwaye zinomlinganiselo wokumelana ongaphezulu kwe-odolo ezilithoba zobukhulu. Zingasetyenziswa njengeebhuleki zombane ukukhupha amandla e-kinetic koololiwe, okanye zibe ncinci kune-square millimeter yezixhobo ze-elektroniki.

Amaxabiso e-Resistor (Amaxabiso akhethwayo)
Kwiminyaka yoo-1950 ukwanda kwemveliso yee-resistor kwadala isidingo semilinganiselo yokumelana eqhelekileyo. Uluhlu lwemilinganiselo yokumelana lulinganiswa ngokwemilinganiselo ebizwa ngokuba yi-preferred values. Amaxabiso akhethwayo achazwa kwi-E-series. Kwi-E-series, ixabiso ngalinye liphezulu ngepesenti ethile kuneyangaphambili. Kukho ii-E-series ezahlukeneyo zokunyamezelana okwahlukeneyo.

Usetyenziso lwe-Resistor
Kukho umahluko omkhulu kwiinkalo zezicelo zeeresistor; ukusuka kwizixhobo ezichanekileyo kwi-elektroniki yedijithali, ukuya kwizixhobo zokulinganisa ubungakanani obuphathekayo. Kule sahluko kudweliswe izicelo ezininzi ezidumileyo.

Abachasi abakwiichungechunge kunye nabahambelanayo
Kwiisekethe ze-elektroniki, ii-resistor zidla ngokudityaniswa ngochungechunge okanye ngaxeshanye. Umzekelo, umyili wesekethe unokudibanisa ii-resistor ezininzi ezinee-standard values ​​(E-series) ukuze afikelele kwixabiso elithile lokuxhathisa. Kuqhagamshelo lwe-series, umbane odlula kwi-resistor nganye uyafana kwaye ukuxhathisa okulinganayo kuyafana nesimbuku see-resistor nganye. Kuqhagamshelo oluhambelanayo, i-voltage edlula kwi-resistor nganye iyafana, kwaye ukuchasana okulinganayo kuyafana nesimbuku see-inverse values ​​kuzo zonke ii-resistor ezihambelanayo. Kwi-articles resistors ezihambelanayo nezilandelanayo zinikwe inkcazo eneenkcukacha yemizekelo yokubala. Ukusombulula iinethiwekhi ezinzima ngakumbi, imithetho yesekethe kaKirchhoff ingasetyenziswa.

Linganisa umsinga wombane (i-shunt resistor)
Umsinga wombane ungabalwa ngokulinganisa ukuhla kwevolthi phezu kwe-resistor echanekileyo enokumelana okwaziwayo, eqhagamshelwe ngokulandelelana nesekethe. Umsinga ubalwa ngokusebenzisa umthetho we-Ohm. Le yi-ammeter okanye i-shunt resistor. Ngokwesiqhelo le yi-resistor echanekileyo kakhulu ye-manganin enexabiso eliphantsi lokumelana.

Izithinteli ze-LED
Izibane ze-LED zifuna umbane othile ukuze zisebenze. Umbane ophantsi kakhulu awuyi kukhanyisa i-LED, ngelixa umbane ophezulu kakhulu unokusitshisa isixhobo. Ke ngoko, zihlala ziqhagamshelwe ngokulandelelana nee-resistor. Ezi zibizwa ngokuba zii-ballast resistors kwaye zilawula umbane kwisekethe ngaphandle kokuphazamiseka.

Isithinteli semoto esivuthuzayo
Kwiimoto inkqubo yokungenisa umoya isebenza yifeni eqhutywa yimoto yomoya. I-resistor ekhethekileyo isetyenziselwa ukulawula isantya sefeni. Oku kubizwa ngokuba yi-resistor yemoto yomoya. Kusetyenziswa uyilo olwahlukeneyo. Uyilo olunye luluhlu lwee-resistor ze-wirewound ezinobukhulu obahlukeneyo kwisantya ngasinye sefeni. Olunye uyilo luquka isekethe edibeneyo ngokupheleleyo kwibhodi yesekethe eprintiweyo.
