Inzwa yokucindezela kwe-capacitive yakhiwe yizicucu ezimbili ezihambayo (i-diaphragm yensimbi enwebekayo), izicucu ezimbili eziqinile (ingubo yensimbi engilazini egobile ku-diaphragm enwebekayo ephezulu nephansi), ama-terminal okukhipha kanye nendlu, njll. Kwakhiwa ama-capacitor amabili ochungechunge phakathi kwepuleti elihambayo namapuleti amabili aqinile. Lapho ingcindezi yokungenisa isebenza ku-diaphragm enwebekayo, i-diaphragm enwebekayo ikhiqiza ukufuduka, okubophezeleka ukuthi kwehlise ibanga ngengxenye eyodwa ezinzile, futhi kwandise ibanga ngengxenye enye ezinzile (kungaboniswa ngephepha). Ibanga phakathi kwama-electrode amabili ensimbi lingenye yezinto ezibalulekile ezithinta i-capacitance, ibanga liyakhuphuka, i-capacitance iyancipha, ibanga liyancipha, i-capacitance iyanda. Lolu hlobo lwesakhiwo lubizwa ngokuthi isakhiwo esihlukile lapho amapharamitha ezinto ezimbili zokuzwa eshintshwa khona ngenani elifanayo kodwa ngokuphambene ngenxa yenani elilinganisiwe.
Uma i-diaphragm elastic ibekwe phakathi kwengcindezi eseceleni kanye nengcindezi yomoya (umgodi ongaphezulu we-diaphragm elastic ungowomoya), ingcindezi elinganisiwe yithebula; Uma i-diaphragm elastic ibekwe phakathi kwengcindezi eseceleni kanye ne-vacuum (umgodi ongaphezulu we-diaphragm elastic udlula ku-vacuum), ingcindezi ephelele iyalinganiswa. Umthamo we-capacitor ulingana ne-dielectric kanye nendawo yayo ephumelelayo phakathi kwamapuleti amabili e-capacitor, futhi ulingana ngokuphambene nebanga eliphakathi kwamapuleti amabili, okungukuthi, i-C=ε A/ D, lapho i-ε iyindawo eqinile ye-dielectric ye-dielectric, i-A iyindawo ephumelelayo phakathi kwama-electrode amabili ensimbi, i-D iwububanzi obuphakathi kwama-electrode amabili ensimbi. Kusukela kulobu budlelwano, kungabonakala ukuthi lapho amapharamitha amabili engashintshi futhi enye ipharamitha isetshenziswa njenge-variable, i-capacitance izoshintsha ngepharamitha eshintshayo.
Kunezinhlobo eziningi zezifunda zokulinganisa ezisetshenziswa nenzwa yokucindezela i-capacitive. Ake sithathe isifunda sebhuloho njengesibonelo ukuze sibonise isimiso sokusebenza sesifunda sokulinganisa inzwa yokuhlukanisa i-capacitance. Ngenxa yokuthi i-capacitance iyipharamitha ye-AC, ibhuloho livuselelwa yi-AC nge-transformer. I-Transformer ikhoyili emibili kanye ne-capacitance yebhuloho, lapho kungekho ngcindezi yokungena, ibhuloho elilinganiselwe, kanye namanani amabili e-capacitance alingana ne-C0, lapho umphumela wokucindezela, enye yenani le-capacitance le-C0 + delta C, enye inani le-capacitance le-C0 - delta, C (i-delta C yokucindezela kwangaphandle okubangelwa ukushintshashintsha kwe-capacitance), ibhuloho elingaphandle kwebhalansi, Lapho inani le-capacitance liphezulu, i-voltage nayo iphakeme, futhi umehluko we-voltage ukhiqizwa phakathi kwama-capacitor amabili, lapho ibhuloho likhiqiza khona umphumela we-voltage u-U omele ingcindezi yokungenisa.
