Resistor wani bangaren lantarki ne mai wucewa don ƙirƙirar juriya a cikin kwararar wutar lantarki. A kusan dukkanin hanyoyin sadarwar lantarki da na'urorin lantarki ana iya samun su. Ana auna juriya a cikin ohms. Ohm shine juriya da ke faruwa a lokacin da na'urar ampere ɗaya ta wuce ta hanyar resistor tare da digon volt ɗaya a kan tashoshi. Halin halin yanzu yana daidai da ƙarfin lantarki a kan iyakar tasha. Ana wakilta wannan raboDokokin Ohm:

Ana amfani da resistors don dalilai da yawa. Misalai kaɗan sun haɗa da ƙayyadaddun wutar lantarki, rabon wutar lantarki, samar da zafi, daidaitawa da lodawa da da'irori, samun iko, da daidaita madaidaicin lokaci. Ana samun su ta kasuwanci tare da ƙimar juriya akan kewayon fiye da umarni tara na girma. Ana iya amfani da su azaman birki na lantarki don ɓatar da kuzarin motsi daga jiragen ƙasa, ko zama ƙasa da milimita murabba'i don kayan lantarki.

Ƙimar Adawa (Dabi'u da aka fi so)
A cikin 1950s ƙara yawan samar da resistors ya haifar da buƙatar daidaitattun ƙimar juriya. An daidaita kewayon ƙimar juriya tare da abin da ake kira ƙimar da aka fi so. An bayyana ƙimar da aka fi so a cikin jerin E. A cikin jerin E, kowane ƙima yana da ƙayyadaddun kaso sama da na baya. Daban-daban E-jerin wanzu don daban-daban tolerances.

Resistant aikace-aikace
Akwai babban bambanci a fannonin aikace-aikace don resistors; daga madaidaicin abubuwan da ke cikin na'urorin lantarki na dijital, har zuwa na'urorin auna don adadi na zahiri. A cikin wannan babin an jera shahararrun aikace-aikace da yawa.

Resistors a cikin jerin kuma a layi daya
A cikin da'irori na lantarki, ana haɗa resistors akai-akai a jere ko a layi daya. Mai zanen da'ira na iya alal misali ya haɗa resistors da yawa tare da daidaitattun ƙima (E-jerin) don isa takamaiman ƙimar juriya. Don jerin haɗin kai, halin yanzu ta kowane resistor iri ɗaya ne kuma daidai da juriya daidai yake da jimlar kowane resistors. Don haɗin layi ɗaya, ƙarfin lantarki ta kowane resistor iri ɗaya ne, kuma juriya daidai yake da jimlar ƙimar juriya ga duk masu tsayayya da juna. A cikin articles resistors a layi daya da jerin an ba da cikakken bayanin misalan lissafi. Don warware har ma da hadaddun cibiyoyin sadarwa, ana iya amfani da dokokin da'irar Kirchhoff.

Auna wutar lantarki (shunt resistor)
Ana iya ƙididdige ƙarfin lantarki ta hanyar auna juzu'in wutar lantarki akan madaidaicin resistor tare da sanannen juriya, wanda aka haɗa a jere tare da kewaye. Ana lissafin halin yanzu ta amfani da dokar Ohm. Wannan shi ake kira ammeter ko shunt resistor. Yawancin lokaci wannan shine babban madaidaicin manganin resistor tare da ƙarancin juriya.

Resistors don LEDs
Fitilar LED suna buƙatar takamaiman halin yanzu don aiki. Ƙarƙashin halin yanzu ba zai haskaka LED ɗin ba, yayin da maɗaukakin halin yanzu zai iya ƙone na'urar. Sabili da haka, ana haɗa su sau da yawa a cikin jerin tare da resistors. Waɗannan ana kiran su ballast resistors kuma suna sarrafa abin da ke cikin kewaye.

Mai iska mai iska
A cikin motoci ana amfani da tsarin iskar iska ta hanyar fanka wanda injin busa ke tukawa. Ana amfani da resistor na musamman don sarrafa saurin fan. Wannan shi ake kira da abin busa motar. Ana amfani da kayayyaki daban-daban. Ɗayan ƙira shine jerin nau'ikan juzu'i daban-daban na girman igiyar waya don kowane saurin fan. Wani zane ya haɗa da cikakken haɗin da'ira akan allon da'ira da aka buga.
