Kweelana le capacitor

A capacitor ngomnye weyona milenze ibaluleke eqhelekileyo eesekethe elektroniki. Iintlobo capacitors, ezinye imida, ezifana kweelana le capacitor, kuxutyushwa kweli nqaku.

Sinokuthi electrode ezimbini metal ezahlulwe sisithuba ngomaleko zezulu, kwaye a capacitor. Ngalinye iipleyiti iye imveliso yawo kwaye ezifakelwe isekethe yombane. Loo isixhobo uneempawu ezithile, yaye omnye wabo kweelana le capacitor.

Capacitor okanye njengoko ibizwa ngokuba, amandla ukuba isixhobo umdla kakhulu. Kwanele ukuba bathi alufanelekanga DC. Ukuba ukhangela le DC kule mbono, kweelana le capacitor mkhulu kakhulu, phantse ongapheliyo DC.

Kwangaxeshanye, lo mzuzu yokuqala xa isikhongozeli ukuya DC yangoku elijikeleza isigxina wayo. Ngaphakathi iinkqubo ezintsonkothileyo zenzeke. Xa capacitance umlandu, flow yangoku phantse liyaphela. Kodwa ke kukho enye caveat, ngenxa umgangatho Heating. Kungakhathaliseki ukuba lihle i yokwambathisa na, sekunjalo akhabanayo ohambe ngayo yangoku lusizi. Ibizwa ukuvuza yangoku.

Loo ukuvuza yangoku kubonisa umgangatho yokwambathisa ezisetyenziswa xa kusenziwa capacitors. Le yokwambathisa ongcono, i ukuvuza yangoku incinane. Apha, umntu ingqalelo imeko ke ombane ukuya capacitance na ityala apho, kukho ngoku ukuvuza ujikeleze lonke ilungu ityala. Ngoko ke, umthetho Ohm siya Ungabala ukuvimba le capacitor. Kuya kuba mkhulu, imisinga ukuvuza kwizikhongozelo namhlanje amaqhezu microamps.

A bit ezahlukeneyo umfanekiso omncinane ukhangela xa capacitor ukuba usethubeni lokuba ifildi yangoku. Ngoku aqukuqela ngokukhululekiyo isitya. Isizathu kukuba kukho inkqubo rhoqo ndiyenza-akanakuhlawulisa capacitor. Inkqubo ye nayiphi flow yangoku enxulumene ilahleko yayo ngenxa yobukho uxhathiso kulo mzekelo, ngaphandle ngcingo ukumelana esebenzayo capacitance langoku le capacitor ngenxa yeenkqubo zayo, ekuzezi ukutshaja nokudubula.

Iimpawu zombane imveliso ogqityiweyo kuxhomekeke kwizinto ezininzi. Ezi ziquka ubume, imilinganiselo zejiyometri, uhlobo Heating. Kukho iintlobo-ntlobo capacitors njenge Heating zisetyenziswa emoyeni, umoya, iplastiki, mica, iphepha, iglasi, iiseramikhi, aluminiyam-electrolyte tantalum electrolyte.

Iintlobo ezimbini yokugqibela ibizwa ngokuba capacitors electrolytic, zikholisa ukuba nomthamo ephakamileyo. Ezinye capacitors wabiza kuhlobo Heating - iphepha, yodongwe, iglasi. Ngamnye kubo uneempawu zawo, ukuziphatha kwabo phantsi parameters ezahlukeneyo umsinga wombane, iimpawu zayo kunye nesicelo.

Ngoko ke, lo capacitors yodongwe bavame kusetyenziswa xa kucocwa ulwelo ngesandla ukuba rhoqo iisekethe ingxolo electrolytic - yokuhluza ingxolo ezitsho eliphantsi. Kwaye kunye uxhulumaniso engumzekelo i capacitors yodongwe kunye electrolytic, kuvela lokucoca ixhaphakileyo ezisetyenziswa phantse zonke izikimu. Kuzo zonke iimeko isikhongozeli lixabiso esisigxina ezifana 0,15 microfarads.

Kuyimfuneko ukuba kuqatshelwe ukuba kukho capacitor variable, kwisikhundla zabo kuyahlukana nedlela indawo iinqanam yolawulo. Oku kuphunyezwa ngokuguqula ukungqubana kwamacwecwe capacitor. Njengoko ityala lolwangazelelo capacitor variable, kukho ekuthiwa-capacitors trimmer. Kuzo, kakhulu, umthamo ungahluka - kodwa ukusa kumkhamo othile kwaye kuphela xa ibakala hlengiso izixhobo.

Le nokuhlelwa esetyenziswa capacitors likhulu - apha uhlobo Heating kunye noyilo.
