Cov capacitors yog cov khoom siv hluav taws xob khaws cia siv hauv cov hluav taws xob hluav taws xob, xws li cov kiv cua lub cav thiab lub tshuab cua txias hauv koj lub tsev. Muaj 2 hom capacitors: electrolytic, uas yog siv rau hauv lub tshuab nqus tsev nqus dej thiab cov kab hluav taws xob transistor, thiab tsis siv hluav taws xob, uas yog siv los tswj kev nce nqi tam sim no. Electrolytic capacitors tuaj yeem ua rau puas vim tias lawv tau txais cov dej ntws ntau dhau lossis khiav tawm ntawm cov electrolyte yog li lawv tsis tuaj yeem tiv taus cov khoom tam sim no. Lub caij no, cov neeg siv hluav taws xob tsis siv hluav taws xob feem ntau puas vim yog lub zog xau. Muaj ntau txoj hauv kev los ntsuas yog tias lub capacitor tseem ua haujlwm tau zoo.
Kauj ruam

Kauj Ruam 6. Saib rau lub txim taws thaum koj ua rau lub davhlau ya nyob twg poob siab
Qhov siv ntawm lub txim hluav taws xob tuaj yeem qhia txog lub peev xwm ntawm lub capacitor.
- Txoj hauv kev no tsuas yog ua haujlwm rau cov khoom siv hluav taws xob uas tuaj yeem tiv taus lub zog los tsim lub txim taws thaum raug hluav taws xob.
- Txoj kev no tsis pom zoo vim nws tsuas yog siv tau rau kev txiav txim siab tus neeg siv lub peev xwm los nqus lub zog thiab tsim lub txim taws thaum raug hluav taws xob. Txoj kev no tsis tuaj yeem siv los ntsuas seb lub peev xwm muaj peev xwm hauv lub capacitor tseem nyob hauv nws qhov kev qhia tshwj xeeb.
- Siv cov txheej txheem no ntawm cov khoom siv hluav taws xob loj tuaj yeem ua rau raug mob hnyav lossis tuag taus!
Lub tswv yim
- Nonelectrolyte capacitors feem ntau tsis yog polarized. Thaum ntsuas cov ntsuas hluav taws xob zoo li no, koj tuaj yeem txuas cov hlau lead ntawm lub voltmeter, multimeter, lossis lwm yam cuab yeej tsim tawm mus rau ib qho ntawm qhov kawg ntawm lub capacitor.
- Nonelectrolyte capacitors tau muab faib ua ob peb hom raws li lawv cov khoom siv hauv paus - ceramic, mica, ntawv, lossis yas - thiab cov yas yas tau muab faib ntxiv rau ntau hom raws li hom yas.
- Cov capacitors siv rau cua sov thiab cua txias tshuab raws li kev ua haujlwm tau muab faib ua ob hom. Khiav hom capacitors ua haujlwm kom tswj tau qhov khiav ntawm qhov hluav taws xob los ntawm cov kiv cua lub cev muaj zog thiab lub tshuab hluav taws xob hauv cov hlawv, cua txias, thiab cua sov twj. Lub caij no, pib lub tshuab hluav taws xob tau siv lub zog loj lub cev muaj zog hauv cov cua sov thiab lub tshuab cua txias kom muab lub zog ntxiv thaum qhib.
- Electrolytic capacitors feem ntau muaj qhov ua siab ntev ntawm 20%. Hauv lwm lo lus, lub capacitor uas tseem zoo yuav muaj peev xwm 20% siab dua lossis tsawg dua nws lub peev xwm ib txwm muaj.
- Nco ntsoov tias koj tsis kov lub capacitor uas tau raug them raws li ua li ntawd tuaj yeem ua rau hluav taws xob rau koj.
