Kodi ma capacitor amagwiritsidwa ntchito bwanji?

Pamapeto pake, ma capacitor amasunga ndalama. Pali zinthu zambiri zomwe mumachita ndi ma capacitor.

Ma capacitor amagwira ntchito bwino kwambiri mu zosefera zamagetsi — kuti asefe ma frequency omwe simukufuna.

Fyuluta yotsika mtengo — ma frequency otsika amaonekera pa output, ma frequency apamwamba amachotsedwa.

Fyuluta yodutsa kwambiri — ma frequency apamwamba amaonekera pa output, ma frequency otsika amadulidwa.

Pogwirizana ndi inductor, amapanga resonator circuit yomwe imatha kudula ma frequency ochepa okha kapena kukulitsa kwambiri ma frequency amodzi.

Fyuluta ya band-pass yomwe imalola ma frequency enieni okha kuti adutse.

Ma capacitor amagwiritsidwa ntchito nthawi zambiri kuthandiza kukhazikika kwa magetsi — popeza amapanga shunt kupita ku AC koma amasiya DC yokha, ngati mukufuna magetsi okhazikika mwina mungagwiritse ntchito ma capacitor kuti muchepetse phokoso, ndikusiya voltage yabwino ya DC yokhazikika pamagetsi otuluka.

Kuyankha kwakanthawi kwa RC circuit kumathandizanso kwambiri pa nthawi.

Yankho laching'ono la RC circuit

Popeza zimatenga nthawi yodziwikiratu kuti zifike pa voteji inayake, zitha kugwiritsidwa ntchito poyesa nthawi yosinthira magetsi.

Nthawi yogwira ntchito ndi nthawi yopuma imayikidwa ndi capacitor ndi resistors awiri mu nthawi yogwirira ntchito yomwe yawonetsedwa pamwambapa.

Apanso, popeza amasunga ndalama, angagwiritsidwe ntchito ngati gawo la dongosolo losinthira AC kukhala DC.

Popanda kugwiritsa ntchito capacitor, m'malo mokhala DC yozungulira, imawoneka ngati sine wave yokhala ndi gawo la pansi lotembenuzidwa mmwamba.

Imeneyo ndi chitsanzo chaching'ono chabe. Amagwira ntchito zambiri, kuphatikizapo kusiyanitsa ndi kuphatikiza (ntchito za calculus), kugawa ma circuits ogwirizana, kusintha kwa voltage kuti abwezere mphamvu, komanso kusunga mphamvu kuti igwiritsidwe ntchito kwakanthawi.

Ndipo pali zinthu zonse zomwe simukufuna kuti capacitance ikhale nazo, koma muyenera kuthana nazo chifukwa capacitance ndi chinthu chenicheni, osati chinthu chomwe chimapezeka pazida zomwe zimachitchula. Monga kulankhulana kwa ma signal cross-talk, kusokoneza input ndi output impedance, kuwonjezera phokoso, kukhala ndi chidwi ndi kugwedezeka kwa mawu, ndi zina zotero.
