1. Iyo capacitor inowanzomiririrwa ne "C" pamwe nenhamba munharaunda (yakadai seC13 inoreva capacitor nhamba 13). Iyo capacitor inoumbwa nemafirimu maviri esimbi ari padyo kune mumwe nemumwe, akaparadzaniswa nechinhu chinodzivirira chiri pakati. Hunhu hweiyo capacitor ndeye DC kusvika AC.

Ukuru hwehuwandu hwehuwandu hwehuwandu hwemagetsi hunogona kuchengetwa.Kuvharidzirwa kwechivharo pachiratidzo che AC kunonzi capacitive reactance, iyo inoenderana nehuwandu uye simba rechiratidzo che AC.

Capacitance XC = 1 / 2πf c (f inomiririra kuwanda kweiyo AC chiratidzo, C inomiririra kugona)

Mhando dzemacapacitor anowanzo shandiswa munhare ielectrolytic capacitors, ceramic capacitors, chip capacitors, monolithic capacitors, tantalum capacitors uye polyester capacitors.

2. Nzira yekuziva: Nzira yekuziva ye capacitor inonyanya kufanana neyo nzira yekuziva yekudzivirira, iyo yakakamurwa kuva marudzi matatu: nzira yakatwasuka, nzira yemavara uye nhamba yemaitiro. Chikamu chekutanga che capacitor chinoratidzwa naFarah (F), uye mamwe mashizha ndeaya: millifa (mF), microfarad (uF), nanofarad (nF), picofarad (pF).

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

Iko capacitance kukosha kwehombe-capacitor yakanyorwa zvakananga pane capacitor, senge 10 uF / 16V.

Iko capacitance value ye capacitor ine diki diki inomiririrwa nemavara kana manhamba pane capacitor.

Tsamba chinyorwa: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF

Digital inomiririra: Kazhinji, manhamba matatu anoshandiswa kuratidza ukuru hwechinzvimbo, maviri ekutanga manhamba anomiririra manhamba akakosha, uye yechitatu manhamba ndiyo magnification.

Somuenzaniso: 102 zvinoreva 10 × 102PF = 1000PF 224 zvinoreva 22 × 104PF = 0.22 uF

3. Kukanganisa tafura ye capacitance

Chiratidzo: FGJKLM

Kukanganisa kunobvumirwa ± 1% ± 2% ± 5% ± 10% ± 15% ± 20%

Semuenzaniso: ceramic capacitor ye104J inoratidza kugona kwe0.1 uF uye kukanganisa kwe ± 5%.
