Mu dera la DC, capacitor ndi yofanana ndi kutsegula dera.Capacitor ndi mtundu wa chigawo chomwe chimatha kusungira magetsi, komanso ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri.zida zamagetsi.Izi zimayamba ndi kapangidwe ka capacitor.Ma capacitor osavuta amakhala ndi mbale za polar kumapeto onse awiri ndi dielectric yotsekera (kuphatikiza mpweya) pakati.Akapatsidwa mphamvu, mbalezo zimayimbidwa, kupanga voteji (kusiyana kothekera), koma chifukwa cha zida zotchingira pakati, capacitor yonse siyimayendetsa.Komabe, nkhaniyi ili pansi pa chikhalidwe chakuti voteji yovuta (yowonongeka) ya capacitor sichidutsa.Monga tikudziwira, chinthu chilichonse chimakhala ndi insulated.Mphamvu yamagetsi pa chinthu ikakwera pang'onopang'ono, zinthu zonse zimatha kuyendetsa magetsi, zomwe zimatchedwa breakdown voltage.Ma capacitors nawonso.Ma capacitors ataphwanyidwa, sakhala ma insulators.Komabe, mu siteji ya sukulu yapakati, ma voltages oterowo samawoneka m'derali, kotero onse amagwira ntchito pansi pa magetsi owonongeka ndipo amatha kuonedwa ngati otetezera.Komabe, m'mabwalo a AC, mayendedwe akusintha kwakanthawi ngati ntchito yanthawi.Njira yolipirira ndi kutulutsa ma capacitor ili ndi nthawi.Panthawiyi, magetsi osinthika amapangidwa pakati pa ma electrode, ndipo magetsi awa amakhalanso ntchito yosintha ndi nthawi.Ndipotu, panopa amadutsa pakati pa capacitors mu mawonekedwe a magetsi.

Ntchito ya capacitor:

●Kuphatikiza:Capacitor yomwe imagwiritsidwa ntchito polumikizira dera imatchedwa coupling capacitor, yomwe imagwiritsidwa ntchito kwambiri pakukana-capacitance coupling amplifier ndi ma capacitive coupling circuits, ndipo imagwira ntchito yodzipatula DC ndikudutsa AC.

●Kusefa:Ma capacitor omwe amagwiritsidwa ntchito m'mabwalo a fyuluta amatchedwa fyuluta capacitors, omwe amagwiritsidwa ntchito mu fyuluta yamagetsi ndi maulendo osiyanasiyana a fyuluta.Zosefera ma capacitor amachotsa ma siginecha mkati mwa gulu linalake la ma frequency kuchokera pa siginecha yonse.

●Kuthetsa banja:Ma capacitor omwe amagwiritsidwa ntchito polumikizira ma circuit amatchedwa decoupling capacitors, omwe amagwiritsidwa ntchito mu DC voltage supply circuits of multistage amplifiers.Decoupling capacitors amachotsa zolumikizira zotsika pafupipafupi pakati pa gawo lililonse amplifier.

●Kuchotsa pafupipafupi kugwedezeka:Capacitor yomwe imagwiritsidwa ntchito pamayendedwe apamwamba kwambiri othamangitsa kugwedezeka amatchedwa high frequency vibration elimination capacitor.Mu audio negative feedback amplifier, kuti athetse kudzidzimuka kwafupipafupi komwe kungachitike, dera la capacitorli limagwiritsidwa ntchito kuthetsa kulira kwafupipafupi komwe kungachitike mu amplifier.

●Kumveka:Ma capacitor omwe amagwiritsidwa ntchito mu LC resonant circuits amatchedwa resonant capacitors, omwe amafunikira mu LC parallel and series resonant circuits.

●Kulambalala:Capacitor yomwe imagwiritsidwa ntchito pozungulira dera imatchedwa bypass capacitor.Ngati chizindikiro mu gulu linalake lafupipafupi chiyenera kuchotsedwa pa chizindikiro chozungulira, dera la bypass capacitor lingagwiritsidwe ntchito.Malinga ndi ma frequency a siginecha yochotsedwa, pali ma frequency amtundu uliwonse (zizindikiro zonse za AC) bypass capacitor circuit ndi high frequency bypass capacitor circuit.

●Kusalowerera ndale:Ma capacitor omwe amagwiritsidwa ntchito m'mabwalo a neutralization amatchedwa neutralization capacitors.Pawayilesi ma frequency apamwamba komanso amplifiers apakatikati ndi ma TV amplifiers apamwamba kwambiri, gawo ili la neutralization capacitor limagwiritsidwa ntchito kuthetsa kudzikonda.

●Nthawi:Ma capacitor omwe amagwiritsidwa ntchito m'mabwalo owerengera nthawi amatchedwa ma capacitor anthawi.Nthawi ya capacitor imagwiritsidwa ntchito pozungulira yomwe imayenera kuwongolera nthawi mwa kuyitanitsa ndi kutulutsa ma capacitor, ndipo ma capacitor amatenga gawo lowongolera nthawi zonse.

●Kuphatikiza:Ma capacitor omwe amagwiritsidwa ntchito m'mabwalo ophatikizana amatchedwa ma capacitor ophatikiza.Mugawo lolekanitsa lopatukana la kusanthula kwamagetsi komwe kungatheke kumunda, chizindikiro chofananira cham'munda chimatha kuchotsedwa pagawo lachidziwitso cholumikizirana pogwiritsa ntchito gawo lophatikizika la capacitor.

●Kusiyana:Ma capacitor omwe amagwiritsidwa ntchito mumayendedwe osiyanasiyana amatchedwa differential capacitors.Kuti mupeze chizindikiro cha spike trigger mu flip-flop circuit, chigawo chosiyana cha capacitor chimagwiritsidwa ntchito kupeza chizindikiro cha spike pulse trigger kuchokera kuzizindikiro zosiyanasiyana (makamaka kugunda kwa rectangular).

●Malipiro:Capacitor yomwe imagwiritsidwa ntchito pagawo lamalipiro imatchedwa compensation capacitor.Mu gawo lolipirira bass la wogwirizira makhadi, gawo locheperako lolipiridwa locheperako limagwiritsidwa ntchito kuwongolera siginecha yotsika pang'ono mu siginecha yosewera.Komanso, pali mkulu pafupipafupi compensation capacitor circuit.

●Bootstrap:Capacitor yomwe imagwiritsidwa ntchito pagawo la bootstrap imatchedwa bootstrap capacitor, yomwe imagwiritsidwa ntchito kwambiri pagawo lotulutsa mphamvu ya OTL amplifier kukulitsa matalikidwe abwino a theka la siginecha ndi mayankho abwino.

●Kugawa pafupipafupi:The capacitor mu frequency division circuit amatchedwa frequency division capacitor.M'gawo logawira mawu pafupipafupi pabokosi lamawu, gawo la frequency division capacitor limagwiritsidwa ntchito kuti chowuzira chokwera kwambiri chizigwira ntchito mu bandi yothamanga kwambiri, cholumikizira cholumikizira chapakatikati chimagwira ntchito mu bandi yapakati-ma frequency ndi otsika-frequency. ntchito zokuzira mawu mu bandi ya low-frequency.

●Katundu:amatanthauza mphamvu yakunja yakunja yomwe imatsimikizira kuchuluka kwa katundu wonyamula katundu pamodzi ndi quartz crystal resonator.Miyezo yodziwika bwino ya ma capacitor onyamula ndi 16pF, 20pF, 30pF, 50pF, ndi 100pF.Kuthekera kwa katundu kumatha kusinthidwa malinga ndi momwe zinthu zilili, ndipo ma frequency ogwirira ntchito a resonator amatha kusinthidwa kukhala mtengo wadzina powusintha.

Pakali pano, makampani opanga mafilimu akulowa mu nthawi ya chitukuko chokhazikika kuchokera ku a
nthawi ya kukula mofulumira, ndipo mphamvu zatsopano ndi zakale za kinetic zamakampani zili mu
siteji ya kusintha.
