1. I-capacitor ngokuvamile imelelwa izinombolo ezithi “C” plus kusekethe (njenge-C13 isho i-capacitor enenombolo 13). I-capacitor yenziwe ngamafilimu amabili ensimbi eduze komunye nomunye, ahlukaniswe yi-insulating material phakathi. Izici ze-capacitor I-DC kuya ku-AC.
Ubukhulu bomthamo we-capacitor yinani lamandla kagesi angagcinwa.Umphumela wokuvimbela we-capacitor esignali ye-AC ubizwa ngokuthi i-capacitive reactance, ehlobene nemvamisa kanye nomthamo wesignali ye-AC.
I-Capacitance XC = 1 / 2πf c (f imele imvamisa yesignali ye-AC, C imele amandla)
Izinhlobo zama-capacitor ezivame ukusetshenziswa ocingweni ama-electrolytic capacitor, ama-ceramic capacitor, ama-chip capacitor, ama-monolithic capacitor, ama-tantalum capacitors nama-polyester capacitor.
2. Indlela yokuhlonza: Indlela yokuhlonza ye-capacitor ngokuyisisekelo iyafana nendlela yokuhlonza ye-resistor, ehlukaniswe yaba izinhlobo ezintathu: indlela evamile eqondile, indlela evamile yombala kanye nendlela evamile yenombolo. Iyunithi eyisisekelo ye-capacitor iboniswa nguFarah (F), kanti amanye amayunithi: millifa (mF), microfarad (uF), nanofarad (nF), picofarad (pF).
Phakathi kwazo: 1 farad = 103 millifarad = 106 microfarad = 109 nanofarad = 1012 picofarad
Inani le-capacitance ye-capacitor yomthamo omkhulu limakwe ngokuqondile ku-capacitor, njenge-10 uF / 16V
Inani le-capacitance ye-capacitor enomthamo omncane limelelwa izinhlamvu noma izinombolo ku-capacitor
Isaziso sencwadi: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF
Ukumelwa kwedijithali: Ngokuvamile, amadijithi amathathu asetshenziselwa ukukhombisa ubukhulu bomthamo, amadijithi amabili okuqala amelela amadijithi abalulekile, kanti idijithi yesithathu iwukukhuliswa.
Isibonelo: 102 kusho 10 × 102PF = 1000PF 224 kusho 22 × 104PF = 0.22 uF
3. Ithebula lephutha lamandla
Uphawu: FGJKLM
Iphutha elivumelekile ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%
Isibonelo: i-ceramic capacitor ye-104J ikhombisa umthamo we-0.1 uF kanye nephutha elingu-± 5%.
