Resistors wasu kayan lantarki ne masu wucewa waɗanda ake amfani da su don sarrafa kwararar halin yanzu a cikin da'ira ta hanyar ba da juriya.Ana amfani da su a cikin nau'ikan da'irori na lantarki iri-iri, daga masu sauƙin LED da'irori zuwa hadaddun microcontrollers.Babban aikin resistor shine tsayayya da kwararar halin yanzu kuma ana auna shi cikin ohms (Ω).
Nau'in resistors
Akwai nau'ikan resistors iri-iri a kasuwa, kowannensu yana da halaye na musamman da aikace-aikace.Wasu na kowa iri na resistors sune
Carbon hade resistors: Wadannan resistors an yi su ne daga carbon da abu mai ɗaure, an ƙera su zuwa siffa mai siffa kuma an lulluɓe su da abin rufe fuska.Suna da ƙananan farashi kuma suna da babban haƙuri ga bambancin zafin jiki.
Resistors Metal Film Resistors: Waɗannan resistors ana yin su ne daga fina-finai na ƙarfe waɗanda aka ajiye akan yumbura.Suna da madaidaicin madaidaici da kwanciyar hankali, yana sa su dace don amfani a cikin madaidaicin da'irori.
Wirewound Resistors: Wadannan resistors ana yin su ne daga raunin waya na karfe a kan yumbu ko tsakiyar karfe.Suna da ƙima mai ƙarfi, yana sa su dace da amfani a manyan aikace-aikacen yanzu.

Halayen masu adawa
Halayen resistors sun bambanta dangane da nau'in resistor da aikace-aikacen.Wasu daga cikin manyan halayen resistors sun haɗa da:
Juriya:Wannan shine mafi mahimmancin halayen resistor kuma ana auna shi cikin ohms (Ω).Ƙimar juriya ta resistor tana ƙayyade adadin abin da zai iya wucewa ta cikinsa.
Haƙuri:Wannan shine adadin bambancin dake tsakanin ainihin juriya na resistor da ƙimar sa na ƙima.An bayyana haƙuri azaman kashi na ƙimar ƙima.
Ƙimar Ƙarfi:Wannan shine matsakaicin adadin ƙarfin da resistor zai iya bacewa ba tare da ya lalace ba.Ana bayyana ƙimar wutar lantarki a watts (W).
Adadin Zazzabi:Wannan shine adadin da juriya na resistor ke canzawa tare da zafin jiki.Ana bayyana ma'auni na yawan zafin jiki a sassa a kowane digiri Celsius (ppm/°C).
A taƙaice, resistors wani muhimmin sashe ne na da'irori na lantarki kuma halaye da nau'in su yakamata a yi la'akari da su a hankali lokacin zabar resistor da ya dace don takamaiman aikace-aikacen.
