Kulimbikira capacitor ndi

capacitor ndicho chimodzi cha zinthu ambiri madera amagetsi. Mitundu ya capacitors, ena mwa magawo, monga kulimbikira kwa capacitor ndi, m'nkhani ino.

Tikhoza kunena kuti awiri zitsulo maelekitirodi ankasiyana wosanjikiza mpweya, ndipo ali capacitor. Aliyense wa mbale ali linanena bungwe ake akhoza chokhudzana ndi dera magetsi. Chotero chipangizo ali ndi makhalidwe ena, ndipo mmodzi wa iwo ndi kulimbikira capacitor lapansi.

Capacitor kapena monga iwo ukutchedwa, timazindikira kuti chipangizo chidwi kwambiri. Wokwanira kuti zilibe pochitika DC. Ngati inu muyang'ana pa DC ku mfundo imeneyi, kulimbikira kwa capacitor ioneka, pafupifupi wopandamalire DC.

Pa nthawi yomweyo, nthawi yoyamba pamene polumikiza chidebe kwa DC dera panopa ndi mlandu wake. Mkati njira zovuta chichitike. Kamodzi capacitance ndi mlandu, otaya panopa pafupifupi ikutha. Koma pali chenjezo limodzi, chifukwa dielectric khalidwe. Ziribe kanthu momwe abwino insulator mwina, Imatsikirabe mu izo panopa womvetsa chisoni. Njirayi imatchedwa kutayikira panopa.

Kuti kutayikira panopa ali zimasonyeza khalidwe la insulator ntchito kupanga capacitors. The insulator bwino, ndi kutayikira panopa n'chochepa. Apa, munthu akhoza kuganizira zinthu zilili ndi voteji amene capacitance ndi mlandu, pali kutayikira panopa umene ukufika mwa membala mlandu. Choncho, ndi lamulo Ohm tingathe kuwerengera impedance wa capacitor lapansi. Iwo adzakhala wamkulu, mafunde kutayikira mu muli masiku ano tuzigawo twa a microamps.

A pang'ono osiyana chithunzi zikuwoneka pamene capacitor akuwululidwa kwa alternating panopa. Current umayenda momasuka kudzera chotengeracho. Chifukwa chake n'chakuti pali njira zonse zimatulutsa-mlandu capacitor. A ndondomeko ya otaya aliyense panopa kugwirizana ndi imfa yake chifukwa kukhalapo kukaniza mu nkhani iyi, kupatula yogwira kukana mawaya pano capacitance wa capacitor chifukwa njira mwake, kutanthauza nawuza ndi lililonse.

The katundu amagetsi a chotsirizidwa kumatengera zifukwa zambiri. Zikuphatikizapo mawonekedwe, kutalika zojambula, mtundu wa dielectric. Pali mitundu yosiyanasiyana ya capacitors monga dielectric ndi ntchito mu zingalowe, mpweya, pulasitiki, Mica, pepala, galasi, ziwiya zadothi, zitsulo zotayidwa-electrolyte tantalum electrolyte.

Mitundu ziwiri zapitazi amatchedwa capacitors electrolytic, kawirikawiri ndi mphamvu apamwamba. capacitors ena otchedwa pa dielectric mtundu - pepala, ceramic, galasi. Aliyense wa iwo ali ndi makhalidwe ake, khalidwe lawo pansi magawo osiyana a magetsi, makhalidwe ake ndiponso ntchito.

Choncho, capacitors ceramic Kawirikawiri ntchito imathandiza kuti mkulu pafupipafupi phokoso madera electrolytic - chifukwa imathandiza phokoso pa mafurikwense otsika. Ndipo pamodzi ndi kugwirizana kufanana kwa capacitors ceramic ndi electrolytic, likukhalira sefa ambiri ntchito pafupifupi ziwembu. Nthawi zonse chidebe ndi phindu lokhazikika monga 0,15 microfarads.

M'pofunika kuona pamaso pa capacitor variable, mu mphamvu zawo zimasiyanasiyana malinga ndi malo a ulamuliro kogwirira kozungulira. Izi zimatheka ndi kusintha alipo wa mbale capacitor. Monga nkhani yapadera ya capacitor variable, pali otchedwa trimmer capacitors. Mwa iwo, inenso, mphamvu zingasiyane - koma zosapitirira malire ndi kokha pa siteji ya zida kusintha.

The nomenclature ntchito capacitors ndi yaikulu - onse mu mtundu dielectric ndi kapangidwe.
