Capacitor yozungulira ndi gawo la circuit lomwe nthawi zambiri limakhala capacitor ndi inductor motsatizana. Capacitor ikatulutsidwa, inductor imayamba kukhala ndi reverse recoil current, ndipo inductor imayikidwa chaji; Pamene voltage ya inductor ifika pamlingo wapamwamba, capacitor imayikidwa chaji, kenako inductor imayamba kutulutsa ndipo capacitor imayamba kuyiyika chaji, ntchito yotereyi imatchedwa resonance. Munjira iyi, inductance imayikidwa chaji ndi kutulutsidwa mosalekeza, kotero mafunde a electromagnetic amapangidwa.

Mu dera lokhala ndi ma capacitor ndi ma inductor, ngati ma capacitor ndi ma inductor ali ofanana, izi zitha kuchitika pakapita nthawi yochepa: mphamvu ya capacitor imawonjezeka pang'onopang'ono, pomwe mphamvu yamagetsi imachepa pang'onopang'ono; Nthawi yomweyo, mphamvu yamagetsi ya inductor imawonjezeka pang'onopang'ono, ndipo mphamvu yamagetsi imachepa pang'onopang'ono. Nthawi ina yaying'ono, mphamvu yamagetsi ya capacitor imachepa pang'onopang'ono, pomwe mphamvu yamagetsi imawonjezeka pang'onopang'ono; Nthawi yomweyo, mphamvu yamagetsi ya inductor imachepa pang'onopang'ono, ndipo mphamvu yamagetsi imawonjezeka pang'onopang'ono. Kuwonjezeka kwa mphamvu yamagetsi kumatha kufika pamtengo wabwino kwambiri, kuchepa kwa mphamvu yamagetsi kumatha kufika pamtengo woyipa kwambiri, ndipo njira ya mphamvu yamagetsi yomweyo idzasinthanso mbali zabwino ndi zoyipa munjira iyi, panthawiyi timatcha kuti kugwedezeka kwamagetsi kwa dera.

Chochitika cha kusinthasintha kwa dera chikhoza kutha pang'onopang'ono, kapena chingapitirirebe chosasinthika. Pamene kusinthasinthaku kukupitirira, timachitcha kuti kusinthasintha kwa amplitude kosalekeza, komwe kumadziwikanso kuti resonance.

Nthawi imene magetsi a capacitor kapena inductor awiri amasinthira pa nthawi imodzi imatchedwa nthawi yobwerezabwereza, ndipo nthawi yobwerezabwereza ya nthawi yobwerezabwereza imatchedwa nthawi yobwerezabwereza. Nthawi yotchedwa nthawi yobwerezabwereza imafotokozedwa motere. Imagwirizana ndi magawo a capacitor C ndi inductor L, omwe ndi: f=1/√LC.

(L ndi inductance ndipo C ndi capacitance)
