Pakupedzisira, ma capacitor anochengetedza mari. Pane zvinhu zvakawanda zvaunoita nema capacitor.
Ma capacitor anoshanda zvakanaka muma electronic filters — kuti abvise ma frequency asingadi.
Sefa yepass yakaderera — mafrequency akaderera anowanikwa pakubuda, mafrequency akakwira anobviswa.
Sefa ye high pass — ma frequency akakwira anowanikwa pakubuda, ma frequency akaderera anobviswa.
Pamwe chete ne inductor, vanogadzira resonator circuit iyo inogona kudimbura huwandu hushoma hwema frequency kana kutowedzera zvakanyanya frequency imwe chete.
Sefa yeband-pass inobvumira ma frequency chaiwo chete kuti apfuure.
Ma capacitor anoshandiswa kakawanda kubatsira kudzikamisa magetsi — sezvo achigadzira shunt kuenda ku AC asi achisiya DC isina, kana uchida magetsi akagadzikana ungangoshandisa ma capacitor kudzivirira ruzha, zvichisiya voltage yeDC yakasimba pamagetsi anobuda.
Mhinduro yenguva pfupi yeRC circuit inobatsirawo zvikuru pakuita nguva.
Mhinduro yechinguvana yeRC circuit
Sezvo zvichitora nguva inofungidzirwa kuti inosvika pamagetsi chaiwo, zvinogona kushandiswa kuronga nguva yekuchinja magetsi nemagetsi.
Nguva yekubuda uye nguva yekubuda zvinogadziriswa ne capacitor uye resistors mbiri mudunhu renguva rinoratidzwa pamusoro apa.
Zvakare, sezvo vachichengetedza chaji, vanogona kushandiswa sechikamu chesystem yekushandura AC kuita DC.
Pasina kushandisa capacitor, pane kuva DC yakakoromoka, inoita semafungu ane sine chikamu chepazasi chakatenderedzwa mudenga.
Ikoko kungori sampuli diki. Dzinoita zvinhu zvakawanda, zvinosanganisira differentiation and integration (calculus functions), decouple biased circuits, shift voltage phase kuti idzorere simba, uye inochengetedza chaji kwenguva pfupi.
Uye pane zvinhu zvese zvausingade kuti capacitance ive nazvo, asi zvaunofanira kugadzirisa nekuti capacitance chinhu chinongoitika, kwete chimwe chinhu chinongowanikwa pamidziyo inochitsanangura chete. Sekutaura kwechiratidzo, kukanganisa input ne output impedance, kuwedzera ruzha, kunzwa acoustic vibrations, nezvimwewo.
