Kapasinar resonant wani ɓangare ne na da'ira wanda yawanci capacitor ne da inductor a layi ɗaya. Idan aka fitar da capacitor, inductor zai fara samun reverse recoil current, kuma inductor zai yi caji; Lokacin da ƙarfin inductor ya kai matsakaicin, capacitor zai yi caji, sannan inductor zai fara fitarwa kuma capacitor zai fara caji, irin wannan aikin reciprocating ana kiransa resonance. A cikin wannan tsari, induction yana ci gaba da caji da kuma fitar da shi, don haka ana samar da raƙuman lantarki.

A cikin da'irar da ke ɗauke da capacitors da inductors, idan capacitors da inductors suna layi ɗaya, yana iya faruwa a cikin ƙaramin lokaci: ƙarfin capacitor yana ƙaruwa a hankali, yayin da wutar lantarki ke raguwa a hankali; A lokaci guda, wutar lantarki ta inductor tana ƙaruwa a hankali, kuma ƙarfin inductor yana raguwa a hankali. A wani ƙaramin lokaci, ƙarfin capacitor yana raguwa a hankali, yayin da wutar lantarki ke ƙaruwa a hankali; A lokaci guda, wutar lantarki ta inductor tana raguwa a hankali, kuma ƙarfin inductor yana ƙaruwa a hankali. Ƙarar ƙarfin lantarki na iya kaiwa ga matsakaicin ƙima mai kyau, raguwar ƙarfin lantarki kuma yana iya kaiwa ga matsakaicin ƙima mara kyau, kuma alkiblar wutar lantarki iri ɗaya kuma zai canza a cikin alkibla mai kyau da mara kyau a cikin wannan tsari, a wannan lokacin muna kiran juyawar wutar lantarki ta da'irar.

Abin da ke faruwa a cikin da'irar juyawar na iya ɓacewa a hankali, ko kuma yana iya ci gaba ba tare da canzawa ba. Idan juyawar ta ci gaba, muna kiranta juyawar girma mai ɗorewa, wanda kuma aka sani da resonance.

Lokacin da ƙarfin wutar lantarki na capacitor ko inductor forges biyu ke canzawa zuwa zagaye ɗaya ana kiransa lokacin resonant period, kuma ana kiran ribar lokacin resonant mitar resonant. Ana bayyana abin da ake kira mitar resonant ta wannan hanyar. Yana da alaƙa da sigogin capacitor C da inductor L, wato: f=1/√LC.

(L shine inductance kuma C shine capacitance)
