1. Capacitor kawirikawiri amaimiridwa ndi "C" kuphatikiza manambala mu dera (monga C13 amatanthauza capacitor nambala 13). Capacitor imapangidwa ndi mafilimu awiri achitsulo oyandikana wina ndi mzake, olekanitsidwa ndi zinthu zotetezera pakati. Makhalidwe a capacitor ndi Ndi DC kupita ku AC.

Kukula kwa mphamvu ya capacitor ndi kuchuluka kwa mphamvu yamagetsi yomwe ingasungidwe.Kutsekereza kwa capacitor pa chizindikiro cha AC kumatchedwa capacitive reactance, yomwe ikugwirizana ndi mafupipafupi ndi mphamvu ya chizindikiro cha AC.

Capacitance XC = 1 / 2πf c (f imayimira ma frequency a siginecha ya AC, C imayimira mphamvu)

Mitundu ya ma capacitor omwe amagwiritsidwa ntchito kwambiri pamafoni ndi ma electrolytic capacitors, ceramic capacitors, chip capacitors, monolithic capacitors, tantalum capacitors ndi polyester capacitors.

2. Njira yozindikiritsira: Njira yozindikiritsira ya capacitor kwenikweni ndi yofanana ndi njira yozindikiritsira yotsutsa, yomwe imagawidwa m'mitundu itatu: njira yowongoka, njira yamtundu wamtundu ndi nambala yokhazikika. Chigawo choyambirira cha capacitor chikuwonetsedwa ndi Farah (F), ndi zigawo zina: millifa (mF), microfarad (uF), nanofarad (nF), picofarad (pF).

Pakati pawo: 1 farad = 103 millifarad = 106 microfarad = 109 nanofarad = 1012 picofarad

Mtengo wa capacitance wa capacitor wamkulu umadziwika mwachindunji pa capacitor, monga 10 uF / 16V.

Mphamvu ya capacitor yokhala ndi mphamvu yaying'ono imayimiridwa ndi zilembo kapena manambala pa capacitor.

Chidziwitso cha kalata: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF

Kuyimira pa digito: Nthawi zambiri, manambala atatu amagwiritsidwa ntchito kusonyeza kukula kwa mphamvu, manambala awiri oyambirira amaimira manambala ofunika, ndipo nambala yachitatu ndiyo kukulitsa.

Mwachitsanzo: 102 amatanthauza 10 × 102PF = 1000PF 224 amatanthauza 22 × 104PF = 0.22 uF

3. Table yolakwika ya capacitance

Chizindikiro: FGJKLM

Cholakwika chovomerezeka ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%

Mwachitsanzo: ceramic capacitor ya 104J imasonyeza mphamvu ya 0.1 uF ndi cholakwika ± 5%.
