Capacitance kagesi

Babashayeli ezimbili, okuyinto ngci komunye nomunye futhi ibekwe eduze yakha capacitor.

Babashayeli obumba icala capacitor belingana nokubaluleka amacala okuphambene.

Kabanzi mkhuba capacitor flat sakhiwe imibuso emibili parallel izingcwecwe zensimbi ezilula ahlukaniswe ungqimba Kwe-dielectric Heating. Ibanga phakathi amapuleti lincane uma liqhathaniswa yobukhulu bawo. Lezi zingqimba capacitor abizwa zezinhlangothi capacitor.

Ukuze ukushaja ipuleti alinganayo amacala okuphambene, kungenzeka ukuba unamathisele ukuba izinti umshini kagesi. Khona-ke phezu ipuleti eyodwa iya icala omubi ngakolunye - icala omuhle.

Ungaxhuma omunye amapuleti ne isigxobo semoto enye emhlabathini; kuyilapho ngakolunye ipuleti ngu lokungeniswa kuphakama icala, belingana nokubaluleka obuhlukile yisibonakaliso ophethe ipuleti kuqala. Uma plate kanye lokushaja omuhle, by ipuleti lokungeniswa ngendlela icala omubi; icala HIV neutralized ngu electron ipuleti, pritekshimi at phansi ipuleti okuyinto umthombo cishe ongashi kubo. Bakhangwe kahle icala ipuleti A, icala negative uzobe elise ebusweni engaphakathi ipuleti zibheke A.

Uma ipuleti A kumbi icala, ama-electron, khulula bacasulwa kusukela ipuleti ku ipuleti A, nihambe ipuleti phansi I ngaleyo ndlela kahle icala.

Kuzo zombili lezi zimo, amacala bagxile kuphela Okusizayo ebhekene evele A no B.

Ukungabikho amacala Laphezu yangaphandle kwenza kube nokwenzeka ukuba ngokuphelele uthumele capacitor amacala emaceleni elingaphandle amapuleti. Ophathwa capacitor kunqunywa ngecala lokuvukela omunye amapuleti alo, njengoba kukhona icala belingana ezidlula komunye by lokungeniswa.

Joyina omunye ungcwecwe capacitor ngezinduku electrometer, kanye nezinye plate kanye electrometer izindlu lusekelwe. Ukusebenzisa bead Uphenyo kuzodlula ngokulandelana capacitor icala izingxenye alinganayo. Siphawula ukuthi ngokwandisa icala izikhathi 2, 3, 4 noma ngaphezulu ngokulandelana, 2, 3, 4 izikhathi noma ngaphezulu kwandisa umehluko ezingaba we capacitor.

Lokhu value, okuyinto kukalwa isilinganiso capacitor kwenkokhiso umehluko ezingaba izingcwecwe zalo (noma amapuleti) kuyinto capacitance we capacitor.

Elisho ke incwadi C, ungabhala:

C = q / (φ1 - φ2).

Inkambu kagesi phakathi amapuleti capacitor kakhulu igxile therein ngakho umzimba kwalo musa kuthinte capacitance we capacitor.

Ukuhlolwa kwenziwa. Thatha capacitor ipuleti siqukethe izingcwecwe zensimbi ezilula ezimbili A no B, zaqiniswa ku insulators.

Xhuma nge plate electrometer A plate njengasezinsukwini lusekelwe. A plate icala, lapho electrometer uphawu ezithile umehluko ongaba khona capacitor. Uma i-zoom ipuleti B A, kungabonwa ukuthi engaba umehluko ipuleti incipha.

Ukwehlisa umehluko ongaba khona amapuleti capacitor nenkokhiso njalo kubonisa ukwanda umthamo wayo.

Ngakho, capacitor Planar ngeke sibe ngaphezu ibanga phakathi amapuleti kuncane noma esingaphansi ukushuba we Kwe-dielectric Heating okuvalelwe phakathi amapuleti.

Ngo ukuguquguquka isihlobo plate plate A phezulu naphansi, sizoshintsha endaweni amapuleti, kukhona Okusizayo ezedlulayo. Nakuba abagcina ukufundwa of the electrometer, kungaba azimisele ukuthi ezinkudlwana endaweni idlulela amapuleti we capacitor, lo mkhulu umthamo wayo. I emikhulu endaweni amapuleti capacitor, lo mkhulu icala singagxila kubo ngalesi ukulingana nekhono.

Masenze omunye ukuhlola. Ukuze uhlele le capacitor amapuleti A no B ukuqhela komunye nomunye, kanti plate kanye kwenkokhelo.

Phawula ubukhulu umehluko angaba namandla lapho emoyeni uba Kwe-dielectric Heating. Manje beka ishidi ingilazi phakathi amapuleti, noma yimuphi omunye yisivikelo; sizobona ukuthi lezi ezingaba umehluko sinciphile. Ukukhulisa ke ezingeni sangaphambilini, kubalulekile ukuze ungeze plate kanti icala. Kule kusobala ukuthi esikhundleni the ungqimba umoya phakathi zezinhlangothi capacitor yimuphi omunye Kwe-dielectric Heating kwandisa umthamo wayo.

Ake S₀ - capacitance capacitor, lapho sikhala phakathi amapuleti alo noma emoyeni, futhi C - umthamo wayo nge ukusetshenziswa Kwe-dielectric Heating.

Kwehlukanisa C no S₀, sithola permittivity Kwe-dielectric Heating ԑ:

ԑ = C / S₀.

Ngakho, elikhulu permittivity we Kwe-dielectric Heating, elikhulu capacitance kagesi we capacitor.
