Plate capacitor chacho mudziyo

Two sandara mahwendefa dzinongoda newokuti mumwe uye vakaparadzana pedyo dielectric, vanoumba sandara capacitor. Ndiro mumiririri nyore pakati capacitors, yakaitirwa kuti kuwanda heteronymic simba. Kana ndiro riri kuzivisa mutariri vakaenzana nokukura asi wakatarisana muna modulus, kuti simba electric munda pakati conductors zvichabviswa kaviri. Akamurairawo reshiyo rimwe conductors kusvikira voltage pakati capacitor ndiro rinonzi yemagetsi chinzvimbo:

C = Q / U

Kana urongwa kwamahwendefa riri kuramba, asi yemagetsi vanokwanisa pakati capacitor anogona kunzi kugara upi vebasa conductors. Munyika dzakawanda gadziriro vezvikwata yemagetsi vanokwanisa - Farad (F). Flat capacitor ane voltage akaenzana Verengai intensities wakadenha conductors (E ₁ + E ₂ ... + E _N ). Vector zvikuru. Kukosha magetsi vachikwanisa ndiyo Proportional zvakananga nzvimbo kwamahwendefa uye inversely Proportional kusvika kure therebetween. Izvi zvinoreva kuti, kuti vawedzere magetsi capacitance yacho capacitor, zvakakodzera kuti nharaunda yakakura mahwendefa, apo achidzikisa kure pakati pavo. Zvichienderana dielectric mundiro capacitor kunogona kuva:

• Paper.
• Mica.
• Polystyrene.
• Ceramic.
• Air.

Pfungwa yacho mudziyo, funga muenzaniso pepa capacitor. Paper kubatwa Paraffin, inoshandiswa iyi, sezvo dielectric. Vakaisa dielectric pakati mbiri foil rinoparadza izvo vanoshumira conductors. Urongwa hwose rwuchipeterwa pamwe, umo mhedziso vari akaiswa kuti riine ive remudunhu magetsi. muenzaniso uyu anoiswa mune zvedongo kana simbi dzimba. Flat mhepo capacitor uye mumwe mutariri okuchengetera mano vari mamiriro zvakafanana, sezvinoita svikiro inoshandiswa dielectric zvinhu, iyo inonzi iri kukudzwa capacitor pachayo. Kana kugadzirisa matambudziko, umo zvakafanira kuwana asingazivikanwi zvakawanda, musakanganwa kushandisa uwandu zvinoratidza insulator - dielectric kuramba of svikiro.

The redhiyo anoshandisa mvura uye chakaoma marudzi capacitors. Liquid capacitors vari electrolytic mhinduro, umo oxidized aruminiyamu ndiro anoiswa. Hazvina fuma ichi pane simbi mhosva. The electrolyte ndiyo mhinduro ine boric asidhi uye dzimwe nezvakasanganiswa. Dry okuchengetera mhando inoumbwa rinopeta rinoparadza matatu, rimwe aruminiyamu uye mumwe - resimbi, uye pakati pavo - paiva gauze akaiswa mushonga wokuuraya ine viscous electrolyte. The mupumburu wacho ukaiswa muimba aruminiyamu mhosva uye akazadzwa nebhitumini. Plate capacitor ane siyana mafomu uye vakaderera mutengo. Zvinosuruvarisa mhando izvi haangavi kutsiva mabhatiri yedu nokuti simba Ndege capacitor iri dikisa, uye akamurairawo nokukurumidza, "leaked". Havasi akakodzera seinokonzera magetsi, asi vane chimwe mukana - apo uchiraira kuburikidza neyamapani nemishonga redunhu pakarepo kupa zvakachengetwa simba.
