The simba pamusoro capacitor uye pakukwanisa kwayo

Kana vaviri mutariri mushumo maviri insulated conductors, pakati pavo pane imwe inonzi zvinogona musiyano, izvo kunoenderana kwakakura vebasa uye geometry pamusoro conductors. Pakadaro, kana mhosva vakaenzana mune nokukura asi wakatarisana ari chiratidzo, unogona kupinda tsanangudzo capacitance, paunogona ipapo kuwana pfungwa sei simba pamusoro capacitor. The zvemagetsi capacitance wegadziriro zvinosanganisira conductors maviri, nhamba imwe mhosva kuna dzingangoitika musiyano pakati conductors.

The simba pamusoro capacitor kunobva capacitance. Rinogona kuzivikanwa Masvomhu pamusoro reshiyo ichi. The simba pamusoro capacitor (payakavakirwa) zvichakurukurwa kuti cheni:

W = (C * U * U ) / 2 = (Q * q) / (2 * C) = Q * U / 2, apo W- nesimba capacitor C ndiko capacitance, U- zvinogona musiyano pakati mahwendefa maviri (voltage) , q- ukoshi muripo uwandu.

The kukosha capacitance anoenderana ukuru uye chimiro muitisi uye dielectric kuti anoparadzanisa conductors izvi. A hurongwa umo yemagetsi munda dzichiitika (vemunyika) chete mune imwe nzvimbo, inonzi condenser. The conductors anoumba mudziyo vanonzi mahwendefa. Ndicho nyore pamasikiro dzinonzi yakafanana-ndiro capacitor.

Chinonyanya nyore mudziyo - maviri sandara mahwendefa ane mano kuitisa magetsi. Mahwendefa aya akarongwa zvakafanana pamusoro (zviduku) kure nemumwe uye vakaparadzana nevanhu marongera kubva insulator. Munda simba pamusoro capacitor mune iyi iri riri vemunyika kunyanya pakati kwamahwendefa. Zvisinei, pedyo micheto kwamahwendefa uye dzakapoteredza nzvimbo kunoitika zvakadaro zvikuru simba nemwaranzi. Zvinonzi akadana mabhuku kuputsanya munda. Kazhinji, Akasarudza kusateerera kwavo uye vanofunga kuti zvose simba pamusoro capacitor iri zvachose pakati kwamahwendefa. Asi mune zvimwe zviitiko zvinonzi zvichiri kufungwa (kunyanya kushandisa nyaya mikroemkostey kana, Ukuwo, Ultra-).

Electric capacitance (saka simba pamusoro capacitor) kunobva kwamahwendefa. Kana tikatarira kuna nzira C = E0 * S / D, apo C- capacitance, E0- zvikuru tsika parameter akadai dielectric dzose (iyi, Vacuum) d- kukosha uye daro pakati mahwendefa, zvinobvira kuti munhu chaicho mhedziso kuti capacitance zvakadaro ndege capacitor iri inversely Proportional kukosha kure pakati mahwendefa uye Proportional kunharaunda yavo zvakananga. Kana nzvimbo pakati electrodes kupedza rwakati dielectric, ipapo simba pamusoro capacitor uye pakukwanisa kwayo zvichawedzera kusvikira E nguva (E iri nyaya - the dielectric dzose).

Saka, tinogona ikozvino kuratidza nzira uye zvinogona simba, iyo rinoungana pakati electrodes maviri (ndiro) ari capacitor: W = Q * E * D . Zvisinei, zviri nyore zvikuru kutaura pfungwa "simba capacitor" kuburikidza kukwanisa: W = (C * U * U) / 2.

Formula zvakafanana uye Serial kwokubatana kuramba rinoshanda chero nhamba capacitors chokuita kuti bhatiri.
