Capacitor wani akwati ne wanda zai iya adana cajin lantarki.Ya ƙunshi zanen ƙarfe guda biyu waɗanda ke kusa da juna, an raba su ta hanyar abin rufe fuska.A cewar daban-daban insulating kayan, daban-daban capacitors za a iya yi.Kamar su: mica, porcelain, paper, electrolytic capacitors, da dai sauransu.

A cikin tsari, an raba shi zuwa kafaffen capacitors da m capacitors.Capacitor yana da juriya mara iyaka zuwa DC, wato capacitor yana da tasirin toshewar DC.Juriya na capacitor zuwa alternating current yana shafar mitar alternating current, wato capacitors na iya iri ɗaya suna ba da amsa daban-daban na capacitive ra'ayi ga madaidaitan igiyoyi na mitoci daban-daban.Me yasa wadannan abubuwan mamaki suke faruwa?Wannan saboda capacitor ya dogara da cajinsa da aikin fitarwa don aiki, lokacin da ba a rufe wutar lantarki s.

Lokacin da mai kunnawa ya rufe S, ƙwararrun electrons ɗin da ke kan tabbataccen farantin capacitor suna jan hankalin tushen wutar lantarki kuma ana tura su kan farantin mara kyau.Saboda kayan da aka rufe a tsakanin faranti biyu na capacitor, electrons kyauta daga faranti mai kyau suna taruwa akan farantin mara kyau.An yi cajin tabbataccen farantin mai kyau saboda raguwar electrons, kuma an yi cajin mummunan farantin saboda karuwa a hankali na electrons.

Akwai yuwuwar bambanci tsakanin faranti biyu na capacitor.Lokacin da wannan bambanci mai yuwuwa yayi daidai da ƙarfin wutar lantarki, cajin capacitor yana tsayawa.Idan wutar ta katse a wannan lokacin, capacitor zai iya kula da wutar lantarki.Don cajin capacitor, idan muka haɗa faranti biyu da waya, saboda yuwuwar bambancin dake tsakanin faranti biyu, electrons za su ratsa ta cikin wayar kuma su koma cikin tabbataccen farantin har sai yuwuwar bambancin dake tsakanin faranti biyu ya zama sifili.

Capacitor yana komawa yanayin tsaka-tsakinsa ba tare da caji ba, kuma babu halin yanzu a cikin waya.Matsakaicin yawan adadin da ake amfani da shi a kan faranti biyu na capacitor yana ƙara yawan caji da fitarwa na capacitor;caji da fitarwa na halin yanzu yana ƙaruwa;ma'ana, tasirin tasirin capacitor akan babban mitar alternating current yana raguwa, wato capacitive reactance karami ne, kuma akasin haka Capacitors suna da babban karfin karfin juyi zuwa low-frequency alternating current.Don sauyawar halin yanzu na mita iri ɗaya.Mafi girman ƙarfin kwandon, ƙarami mai ƙarfi na reactance, kuma ƙarami mai ƙarfi, mafi girman amsawar capacitive.
