Nchifukwa chiyani capacitor imatseka DC koma imadutsa AC?

Capacitor ndi mbale ziwiri zofanana zomwe palibe kulumikizana kwamagetsi pakati pawo. Waya umalumikizidwa ku mbale iliyonse. Ma mbale amatha kukhala ndi malo akulu kwambiri komanso mpata wochepa kwambiri pakati pawo. Angapangidwe kuchokera ku mapepala awiri a zojambulazo ndi pepala pakati pawo ndipo chinthu chonsecho chimakulungidwa kuti chikhale chopapatiza. Koma akadali mbale ziwiri zazikulu zokhala ndi mpata pakati pawo.

Ngati mulumikiza batire ku mawaya awiriwa, mphamvu yochepa idzayenda kwa kanthawi kochepa. Idzakankhira ma elekitironi pa mbale imodzi ndikuyamwa ma elekitironi pa mbale inayo. Posachedwapa, pali kusiyana kwa mphamvu pakati pa mbale ziwirizi (zofanana ndi mphamvu ya batire) ndipo palibe mphamvu ina yomwe ikuyenda. Yayima. Imeneyo ndi gawo la DC loletsa. Mphamvu yamagetsi yolunjika singathe kuyenda chifukwa palibe njira yoti idutse pakati pa mbalezo.

Tsopano tiyerekeze kuti talumikiza batire kwa nanoseconds zochepa. Munthawi yochepa imeneyo, ma elekitironi ochepa amayamwa kuchokera pa mbale imodzi ndipo nambala yofanana imayikidwa pa mbale inayo. Pali malo amagetsi pakati pa mbale ziwirizi chifukwa chokhala ndi ma elekitironi ambiri mbali imodzi kuposa inayo. Koma magetsi sanakulitsebe mphamvu ya batire chifukwa tinangolumikiza kwa kanthawi kochepa kwambiri.

Tsopano, sinthani mabatire mwachangu. Tsopano tikuyamwa ma elekitironi kuchokera komwe tidawakankhira kale ndipo tikukankhira ena kumbali ina komwe tidachotsapo ena kale. Tiyeni tichite izi kwa ma nanosecond awiri. Tsopano tasintha mkhalidwewu ndipo tili ndi gawo lamagetsi losiyana pakati pa ma plate. Koma timangolola mphamvu yamagetsi kuyenda kwa kanthawi kochepa kwambiri. Sikokwanira kuti iwonjezere mphamvu yamagetsi ya batire.

Pitirizani kubwereza zimenezo, mukusintha njira ya magetsi, koma mukuchita izi mwachangu kwambiri kotero kuti sizimadzaza. Imeneyo ndi magetsi osinthasintha. Ma circuits amachita ngati magetsi akuyenda m'ma plates. Sikuti kwenikweni akuyenda, koma magetsi amachita ngati AC ikuyenda kudzera mu capacitor.
