Udindo ndi Ntchito ya Ma Capacitors mu Zamakono Zamakono
Ma capacitor amapezeka paliponse padziko lonse lapansi zamagetsi, zomwe zimagwira ntchito ngati zofunikira zomwe zimagwira ntchito zingapo zofunika. Kaya amapezeka mu chipangizo chosavuta cha m'nyumba kapena makina ovuta a mafakitale, ma capacitor ndi ofunikira pakugwira ntchito komanso kuyendetsa bwino kwa mabwalo amagetsi. Nkhaniyi ikuyang'ana pa ntchito zambiri za ma capacitor, kufufuza mfundo zawo, ntchito, ndi zotsatira zake pa zamagetsi zamakono.
1. Kumvetsetsa Zoyambira za Capacitors
Pakatikati pake, capacitor ndi yopanda pakechigawo chamagetsizomwe zimasunga mphamvu zamagetsi m'munda wamagetsi. Amakhala ndi mbale ziwiri zoyendetsa zosiyanitsidwa ndi zida za dielectric, zomwe zimakhala ngati insulator. Mphamvu yamagetsi ikagwiritsidwa ntchito pama mbale, gawo lamagetsi limayamba kudutsa dielectric, zomwe zimapangitsa kuti pakhale mtengo wabwino pa mbale imodzi ndikuthiramo zoipa pa inayo. Mphamvu yosungidwayi imatha kumasulidwa ikafunika, kupangitsa ma capacitor kukhala ofunika pamagwiritsidwe osiyanasiyana.
1.1Capacitance ndi Zosankha Zake
Kuthekera kwa capacitor kusunga ndalama kumayesedwa ndi mphamvu yake, yosonyezedwa mu farads (F). Capacitance imagwirizana mwachindunji ndi malo apansi a mbale ndi dielectric nthawi zonse za zinthu zomwe zimagwiritsidwa ntchito, komanso mosiyana ndi mtunda wapakati pa mbale. Mitundu yosiyanasiyana ya ma capacitor amapangidwa mosiyanasiyana kuti agwirizane ndi magwiridwe antchito, kuyambira ma picofarad (pF) mumayendedwe othamanga kwambiri mpaka ma farads mu ma supercapacitor omwe amagwiritsidwa ntchito posungira mphamvu.
