1. I-capacitor imelwe ngokubanzi ngokuthi "C" kunye namanani kwisekethe (afana ne-C13 ithetha i-capacitor enombolo 13). I-capacitor yenziwe ngeefilimu ezimbini zetsimbi ezisondeleyo komnye nomnye, zihlulwe yinto ekhuselayo phakathi. Iimpawu ze-capacitor ziyi-DC ukuya kwi-AC.
Ubungakanani bomthamo we-capacitor ngumlinganiselo wamandla ombane anokugcinwa.Impembelelo yokuthintela i-capacitor kwi-AC signal ibizwa ngokuba yi-capacitive reactance, ehambelana nokuphindaphinda kunye ne-capacitance yesignali ye-AC.
I-Capacitance XC = 1 / 2πf c (f imele ukuphindaphinda kwesignali ye-AC, i-C imele amandla)
Iindidi ze-capacitors ezisetyenziswa ngokuqhelekileyo kwiifowuni zi-electrolytic capacitors, i-ceramic capacitors, i-chip capacitors, i-monolithic capacitors, i-tantalum capacitors kunye ne-polyester capacitors.
2. Indlela yokuchonga: Indlela yokuchonga ye-capacitor ngokusisiseko iyafana nendlela yokuchonga ye-resistor, eyahlulahlulwe yaba ziindidi ezintathu: indlela yomgangatho othe tye, indlela yomgangatho wombala kunye nendlela yomgangatho wenombolo. Iyunithi eyisiseko ye-capacitor ibonakaliswa nguFarah (F), kunye nezinye iiyunithi: millifa (mF), microfarad (uF), nanofarad (nF), picofarad (pF).
Phakathi kwabo: 1 farad = 103 millifarad = 106 microfarad = 109 nanofarad = 1012 picofarad
Ixabiso le-capacitance ye-capacitor yomthamo omkhulu iphawulwe ngokuthe ngqo kwi-capacitor, njenge-10 uF / 16V
Ixabiso le-capacitance ye-capacitor enomthamo omncinci imelwe ngoonobumba okanye amanani kwi-capacitor
Ileta yeleta: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF
Ukumelwa kwedijithali: Ngokuqhelekileyo, amanani amathathu asetyenziswa ukubonisa ubungakanani bomthamo, amanani amabini okuqala amele amanani abalulekileyo, kwaye idijithi yesithathu kukwandiswa.
Umzekelo: i-102 ithetha i-10 × 102PF = 1000PF 224 ithetha i-22 × 104PF = 0.22 uF
3. Itheyibhile yempazamo yobuchule
Uphawu: FGJKLM
Imposiso evumelekileyo ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%
Umzekelo: i-ceramic capacitor ye-104J ibonisa umthamo we-0.1 uF kunye nephutha le-± 5%.
