Kev taw qhia txog cov khoom siv hluav taws xob ntau (F)

2. Capacitor

Capacitors, zoo li tactile keyboards, yog cov khoom siv hluav taws xob ntau.Lwm tus neeg tsim khoom kuj hu rau qhov hloov tactile li tact switch, laub khawm hloov, lossis lub teeb kov hloov, thiab lwm yam.

A. Lub ntsiab lus ntawm capacitor
Lub capacitor, feem ntau hu ua yooj yim raws li nws lub peev xwm los tuav tus nqi, yog sau los ntawm tsab ntawv C.
Lus Txhais 1: Lub capacitor, raws li nws lub npe qhia, yog 'lub thawv hluav taws xob', ib qho khoom siv uas tuav cov nqi hluav taws xob.Lub npe lus Askiv: capacitor.Capacitors yog ib qho ntawm cov khoom siv hluav taws xob siv dav hauv cov khoom siv hluav taws xob.Lawv tau dav siv nyob rau hauv kev sib cais ntawm Circuit Court, coupling, bypass, filtering, tuning voj, lub zog hloov dua siab tshiab, tswj thiab lwm yam.
Kev txhais 2: lub capacitor.ob lub conductors (nrog rau cov xov hlau) uas yog insulated los ntawm ib leeg thiab nyob ze spaced ua ib tug capacitor.Capacitor txawv ntawm cov capacitor.

B. Kev siv cov capacitors
(a).Kev rho tawm DC: txoj haujlwm yog los tiv thaiv dc los ntawm kev hla thiab cia AC hla dhau.
(b).Bypass (decoupling): Muab txoj kev tsis tshua muaj impedance rau qee cov khoom sib txuas hauv AC Circuit Court.
(c).Coupling: Ib qho kev sib txuas ntawm ob lub voj voog uas tso cai rau cov teeb liab ac hla dhau thiab xa mus rau lub voj voog tom ntej.
(d).Lim: qhov no yog qhov tseem ceeb heev rau DIY, lub capacitor ntawm daim npav daim npav yog lub luag haujlwm no.
(e).Kev them nyiaj kub: txhawm rau txhim kho kev ruaj ntseg ntawm Circuit Court los ntawm kev them nyiaj rau qhov cuam tshuam ntawm qhov tsis txaus adaptability ntawm lwm cov khoom rau qhov kub thiab txias.
(f).Sijhawm: Lub capacitor yog siv ua ke nrog cov resistor los txiav txim lub sij hawm tas li ntawm Circuit Court.
(g).Tuning: Systematic tuning of zaus-dependent circuits, xws li xov tooj ntawm tes, xov tooj cua, TV teeb.
(h).Rectification: Txhawm rau qhib lossis tua tus neeg xyuas pib hloov lub rooj sib txoos ntawm lub sijhawm tau teem tseg.
(i).Lub zog cia: khaws cia hluav taws xob tso tawm thaum tsim nyog.Xws li lub koob yees duab flash, khoom siv cua sov thiab lwm yam.(Hnub no, qee lub capacitors tuaj yeem khaws lub zog ntau npaum li lithium-ion roj teeb, thiab ib lub capacitor tuaj yeem siv lub xov tooj ntawm tes rau ib hnub.
