Ukuqonda indlela iCapacitor esebenza ngayo: Ukuntywila ngokunzulu ekusebenzeni, usetyenziso, kunye neMpembelelo

IiCapacitors zikho yonke indawo kwihlabathi le-elektroniki, zisisiseko ekusebenzeni kwezixhobo ezininzi kunye neenkqubo. Zilula kuyilo lwazo kodwa ziguquguquka ngokuphawulekayo kwizicelo zazo. Ukuyixabisa ngokwenene indima yee-capacitors kwitekhnoloji yale mihla, kubalulekile ukuphonononga kulwakhiwo lwabo, imigaqo esisiseko, indlela yokuziphatha kwiisekethe, kunye nobubanzi bezicelo zabo. Olu phononongo lubanzi luya kubonelela ngokuqondwa ngokucokisekileyo malunga nendlela ii-capacitors ezisebenza ngayo, ukwandisa kwiimpembelelo zabo kwitekhnoloji kunye namandla abo ekamva.

Ulwakhiwo olusisiseko lweCapacitor

Kwisiseko sayo, i-capacitor iqukethe iipleyiti ezimbini ze-conductive ezihlukaniswe yi-insulating material eyaziwa ngokuba yi-dielectric. Esi sakhiwo sisisiseko sinokufezekiswa ngeendlela ezahlukeneyo, ukusuka kwi-parallel-plate capacitor ukuya kuyilo olunzima ngakumbi njenge-cylindrical okanye i-spherical capacitors. Iipleyiti ze-conductive zenziwe ngesinyithi, njenge-aluminium okanye i-tantalum, ngelixa izinto ze-dielectric zinokusuka kwi-ceramic ukuya kwiifilimu ze-polymer, kuxhomekeke kwisicelo esithile.

Amacwecwe axhunyiwe kwisekethe yangaphandle, ngokuqhelekileyo ngee-terminals ezivumela ukusetyenziswa kwe-voltage. Xa i-voltage isetyenziswe kuwo wonke amacwecwe, intsimi yombane ikhiqizwa ngaphakathi kwe-dielectric, ekhokelela ekuqokeleleni kweentlawulo kwiiplate-ezilungileyo kwisitya esinye kunye nebi kwenye. Olu lwahlulo lwentlawulo yindlela esisiseko esetyenziswa ngayoii-capacitorsgcina amandla ombane.

IFiziksi eNgemva koGcino lweTyala

Inkqubo yokugcina amandla kwi-capacitor ilawulwa yimigaqo ye-electrostatics. Xa i-voltage

I-V isetyenziswe kwiiplate ze-capacitor, indawo yombane

I-E iphuhlisa kwi-dielectric material. Le ntsimi yenza amandla kwii-electron zamahhala kwiipleyiti ze-conductive, ezibangela ukuba zihambe. Ii-electron ziqokelelana kwipleyiti enye, zenza umrhumo ongalunganga, ngelixa elinye ipleyiti lilahlekelwa zii-electron, libe lityala eliqinisekileyo.

Izinto zedielectric zidlala indima ebalulekileyo ekwandiseni isakhono se-capacitor yokugcina intlawulo. Yenza oko ngokunciphisa intsimi yombane phakathi kwamacwecwe kwixabiso elinikiweyo lentlawulo egciniweyo, eyandisa ngokufanelekileyo i-capacitance yesixhobo. Ukubanakho

3. Izinto zeDielectric: Uhlobo lwe-dielectric luchaphazela amandla e-capacitor ukugcina intlawulo. Izinto eziphathekayo ezine-dielectric constant constant (permittivity) zandisa i-capacitance.

Ngokwezinto ezisebenzayo, ii-capacitors zidla ngokuba ne-capacitances ukusuka kwi-picofarads (pF) ukuya kwi-farads (F), kuxhomekeke kubungakanani bazo, uyilo, kunye nokusetyenziswa okujoliswe kuko.

Ukugcinwa kwamandla kunye nokukhululwa

Amandla agcinwe kwi-capacitor ngumsebenzi we-capacitance yayo kunye nesikwere sombane kwiiplate zayo. Amandla

I-E egciniweyo ingabonakaliswa ngolu hlobo:

Le equation ibonisa ukuba amandla agcinwe kwi-capacitor ayanda kunye ne-capacitance kunye ne-voltage. Okubalulekileyo, indlela yokugcina amandla kwi-capacitors ihluke kwiibhetri. Ngelixa iibhetri zigcina amandla ngokwekhemikhali kwaye ziwakhulule kancinci, ii-capacitors zigcina amandla ngombane kwaye zinokuwakhulula ngokukhawuleza. Lo mahluko wenza ukuba ii-capacitors zilungele izicelo ezifuna ukuqhuma kwamandla okukhawulezayo.

Xa isiphaluka sangaphandle sivumela, i-capacitor inokukhupha amandla ayo agcinwe, ikhulule intlawulo eqokelelweyo. Le nkqubo yokukhupha inokwenza amandla amacandelo ahlukeneyo kwisekethe, kuxhomekeke kumthamo we-capacitor kunye neemfuno zesekethe.

   U-Z we-capacitor kwisekethe ye-AC unikwa ngu:

    

   $Z=12\pi fCZ\; =\; \backslash frac\{1\}\{2\backslash pi\; fC\}$

    
   

Aphof kukuphindaphinda kophawu lwe-AC. Le equation ibonisa ukuba i-impedance ye-capacitor iyancipha ngokunyuka kwamaxesha amaninzi, okwenza i-capacitors ibe luncedo ekucoceni izicelo apho banokuvala khona izibonakaliso ezisezantsi (ezifana ne-DC) ngelixa zivumela izibonakaliso ze-high-frequency (ezifana ne-AC) ukuba zidlule.
