Magetsi capacitance wa capacitor kuti: chikhalidwe ndi maonekedwe chachikulu

Onse mafakitale ndi tsiku ndi tsiku amafunika chilengedwe cha ambiri zabwino ndi zoipa milandu magetsi. Zikuonekeratu kuti ndi electrification wa matupi ndi a kupatsidwa ulemu electrostatic kuti n'zosatheka. Iwo likukhalira kuti mukusowa chipangizo wapadera. Chotero chipangizo akutumikira monga condenser a.

The capacitor ndi dongosolo losavuta wopangidwa mwa dielectric kulekanitsa mbale ziwiri. Nkofunika kuti makulidwe a insulator anali yochepa polingana ndi kukula kwa mbale zomwezi, mwachitsanzo akuwauza.

Mawonekedwe zosavuta chipangizo zamagetsi capacitive ndi lathyathyathya capacitor, zomwe ndi zovuta mbale awiri zitsulo ankasiyana dielectric a. Ngati mbale izi ya magetsi, phindu kachulukidwe ya mavuto akuwuka pakati pa munda magetsi ndi pafupifupi nthawi kuposa mphamvu yomweyo mmodzi wa mbale izi.

Chizindikiro chofunika kwambiri a dongosolo lino magetsi capacitance. capacitance magetsi ya capacitor mawu a zapansi zamagetsi liri chiŵerengero cha mtengo mmodzi wa mbale ku voteji ntchito pakati pa ochititsa pogwiritsa. Nthawi zambiri, capacitance magetsi a capacitor ndi motere:

C = Q / U

Ngati malo a mbale danga amakhalabe zikutsatiridwa kwa nthawi yaitali, capacitance magetsi a capacitor akhala nthawi zonse (kaya mlandu kachulukidwe pa zipangizo).

Mu System mayiko a miyezo thupi la capacitance magetsi a capacitor ndi amayezedwa farads (F). Malinga ndi gulu ili, farad wina amadziwika magetsi capacitance chipangizo chotero imene voteji pakati insulators ndi Volt limodzi, ndi kuchuluka mlandu umene umagwiritsidwa kwa mbale, ndi wofanana m'khosi wina.

Ndipotu, farad chimodzi - ichi ndi phindu lalikulu kwambiri, choncho kwambiri amagwiritsidwa ntchito mayunitsi monga microfarad, ngakhalenso Nanofarad PF.

Lathyathyathya magetsi capacitance wa capacitor kudzadalira dera maelekitirodi ake ndipo udzakhala wautali pamene kuchepetsa mtunda wa pakati pawo. Kuti kwambiri pa mphamvu zamagetsi mwa zipangizozi umayamba pakati pa ochititsa kapena dielectric wina.

Nthawi zambiri, maelekitirodi kwa capacitors anapanga kuchokera zojambulazo woonda ndi gasket monga pachimake ntchito pepala, Mica kapena ceramic. Mogwirizana ndi chuma kutumikira monga maziko a dielectrics, capacitors, ndipo dzina lawo - pepala, ceramic, mpweya, Mica. Mwachilungamo ambiri M'zaka zaposachedwapa analandira capacitors electrolytic amene mokwanira yaying'ono miyeso ndi ndithu mphamvu ya magetsi. Chifukwa cha makhalidwe amenewa, iwo ankagwiritsa ntchito zipangizo banja, komanso rectifier panopa.

Capacitors ndi imodzi yofunika kwambiri zipangizo zamagetsi, popanda zomwe zingakhale sangathe kukhala ndi ambiri m'banja ndi zipangizo zamagetsi.
