Juriya da capacitor

A capacitor ne daya daga cikin na kowa abubuwa na lantarki. Iri capacitors, wasu daga cikin sigogi, kamar da juriya na capacitor, tattauna a wannan labarin.

Za mu iya cewa biyu karfe wayoyin rabu da wani Layer na iska, kuma yana da capacitor. Kowace daga cikin faranti na da fitarwa da kuma za a iya haɗa wani lantarki kewaye. Irin wannan na'urar yana da wasu halaye, kuma daya daga cikinsu shi ne tsayin dakan da capacitor.

Capacitor ko kamar yadda shi ne ake kira, da damar zama da ban sha'awa sosai na'urar. Isar da shi a ce shi ba ya wuce DC. Idan ka duba a DC daga wannan ra'ayi, da juriya na capacitor ne manya-manyan, kusan iyaka DC.

A daidai wannan lokaci, na farko lokacin da a haɗa da ganga zuwa DC kewaye halin yanzu shi ne ta cajin. Ciki da hadadden tsarin faru. Da zarar capacitance aka caje, yanzu kwarara kusan ceases. Amma akwai wani gargadi, saboda da dielectric quality. Duk yadda mai kyau da wani insulator iya zama, har yanzu gudana ta hanyar da shi yanzu zullumi. Shi ne ake kira yayyo halin yanzu.

Wannan yayyo yanzu ne da ke nuni da ingancin insulator amfani a yi na capacitors. A mafi alhẽri insulator, da yayyo halin yanzu shi ne karami. A nan, wanda zai iya la'akari da shã'aninku ne ƙarfin lantarki ga abin da capacitance aka caje, akwai wani yayyo halin yanzu wanda gudana ta hanyar da cajin memba. Saboda haka, ta Ohm ta dokar za mu iya lissafta da impedance na capacitor. Yana zai zama mai girma, yayyo igiyoyin a zamani kwantena ne kasarun adadi na microamps.

A kadan daban-daban hoto ya dubi lokacin da capacitor ne fallasa zuwa wani alternating halin yanzu. Yanzu gudana yardar kaina ta hanyar jirgin ruwa. Dalilin shi ne, akwai wani tsari da kullum sallame-cajin capacitor. A aiwatar da duk wani halin yanzu kwarara hade tare da asarar saboda gaban da juriya a cikin wannan harka, kuma da aiki da juriya wayoyi ba capacitance na capacitor saboda da matakai, wato caji da dakatar da.

A lantarki Properties na ƙãre samfurin dogara a kan al'amurra da dama. Wadannan sun hada da siffar, na lissafi girma, da irin dielectric. Akwai daban-daban iri capacitors matsayin dielectric ake amfani da su a wani wuri, iska, roba, Mica, takarda, gilashin, tukwane, aluminum-electrolyte Tantalite electrolyte.

A karshe iri biyu suna kira electrolytic capacitors, da suka saba da hakan iya aiki. Sauran capacitors kira a dielectric irin - takarda, yumbu, gilashin. Kowace daga cikinsu yana da halaye, da hali a karkashin daban-daban sigogi na da lantarki, da halaye da kuma aikace-aikace.

Saboda haka, yumbu capacitors aka fi sau da yawa amfani a tace for high mita amo haihuwarka electrolytic - for tace amo a low mitoci. Kuma tare da layi daya dangane da yumbu da kuma electrolytic capacitors, shi dai itace mafi kowa tace amfani a kusan dukkanin makircinsu. A cikin dukkan lokuta da ganga ne tsayayyen darajar kamar 0,15 microfarads.

Wajibi ne a lura da kasancewar wani m capacitor, a ƙãruwa dabam dangane da matsayin na kula da ƙurma. Wannan shi ne cimma by canza zoba na capacitor faranti. Kamar yadda na musamman idan akwai wani m capacitor, akwai abin da ake kira trimmer capacitors. A cikinsu, kuma, da damar su iya bambanta - amma na kuncin da kawai a mataki na kayan aiki gyara.

A nomenclature amfani a capacitors ne babbar - biyu a cikin dielectric irin da ta zane.
