Yadda a Kiyaye Tafkin Capacitance na Capacitor

Amsa tafki da capacitance na capacitor yana iya samun shi cikin hanyoyi daban-daban, kawai da gudanar da parametoci fisis na capacitor. An tsara capacitance C na capacitor da wannan formula:

idani:

• C shine capacitance, ake saki a farads (F).

• ϵ shine permittivity, wanda yake gina ne kan material dielectric da ake amfani a matsayin capacitor.

• A shine area na plates, ake saki a square meters (m²).

• d shine distance bayan plates, ake saki a meters (m).

Hanyoyi don Kiyaye Tafki

Kiyaye Area A:

Hanya: Kiyaye area effective na plates na capacitor.

Muhimmi: Kiyaye area zai kiyaye capacitance direct.

Misali: Idan area na plate na original shine A, kiyayen ta zuwa A/2 zai kiyaye capacitance zuwa na biyu.

Zama Spacing d:

Hanya: Zama distance bayan plates na capacitor.

Muhimmi: Zama spacing zai kiyaye capacitance direct.

Misali: Idan spacing na plate na original shine d, zaman ta zuwa 2d zai kiyaye capacitance zuwa na biyu.

Gudanar Material Dielectric:

Hanya: Amfani da material da permittivity ϵ da ita da take sauti.

Muhimmi: Permittivity da take sauti zai bude capacitance da take sauti.

Misali: Idan material dielectric na original ya da permittivity ϵ1, kawo al'adu da ya da permittivity ϵ2 idan ϵ2<ϵ1 zai kiyaye capacitance.

Tambayar da Musamman

Tambayar da Design:

A lokacin da ake design capacitor, yana da kyau a duba abubuwan da suka fiye waɗannan kamar value capacitance, operating voltage, da frequency characteristics.

Misali, kiyayen area na plate ko zaman spacing yana iya kiyaye maximum operating voltage na capacitor saboda wannan abubuwa sun haifi breakdown voltage.

Zabi Material:

Zabi material dielectric daidai yana haifi capacitance, temperature characteristics, losses, da stability na capacitor.

Misali, wasu materials ceramic suna da permittivity da take sauti amma zai iya haifar da performance da ba daidai a wurare mai yawa.

Process Manufacturing:

A lokacin da manufacturing, haihuwar da plates za su ci gaba da uniform don haifar da electric field irregularities localised wanda zai iya haifar da dielectric breakdown.
