Types of capacitors: na-eme na adịghị ike

A capacitor bụ kọmputa ngwaọrụ nke na-enye ohere na-echekwa na mgbe ahụ na-anapụta ihe ọkụ n'ahụ. The isi e ji mara nke mmewere bụ ya ike, ikpebi ihe-ndebe voltaji na nduzi.

Iche iche ngwaọrụ hapụ teknụzụ ekwe na-emepụta ụdị dị iche iche nke ngwaọrụ. Site ikuku condensers agụnye isiokwu nke dielectric bụ ikuku. The uru nke ụdị ngwaọrụ bụ ala nke rụpụta. Ha na-e maka n'ibu akara ikike na na-haziri maka na-aga n'ihu n'ibu mmetụta. The ọghọm nke ụdị ngwaọrụ gụnyere akwusighi, ogbenye pụrụ ịdabere, ndị dabeere na iru mmiri na okpomọkụ nke na-ajụ, nnukwu size, dịtụ ala dielectric ike nke a na-ejedebeghị ikuku mmebi n'etiti sinkers na ala capacitance.

E nwere akwụkwọ na ụdị capacitors, nke-eme dị ka a dielectric transformer mmanụ impregnated akwụkwọ. Ndị a na ngwaọrụ nwere a elu dielectric ike na ntụkwasị obi. Mgbe a dị elu voltaji , ha nwere a elu capacitance na ala leakage ugbu a.

Ọtụtụ capacitors na-emepụta na a akwụkwọ ndabere maka ike osisi. Iji mee nke a, n'ogige atụrụ ọnụ abụọ efere, n'etiti nke akwụkwọ. The ngwaọrụ mgbe lakpuru a mpịakọta na enịm ke a ite, nke jupụtara na transformer mmanụ na mgbe a kara akara. The ọghọm nke ngwaọrụ gụnyere a otutu aro, elu onwe-inductance na-eguzogide.

Electrolytic capacitors nwere dielectric ụdị, ọkọnọ n'ụdị ihe oxide oyi akwa kpụrụ n'elu nke nọ n'ọrụ metal (na-emekarị aluminum). The ngwaọrụ emepụta site ịtụkwasị na electrolyte mere nke na-arụsi ọrụ metal teepu, n'elu nke a film a kpụrụ si a inogide oxide, ikwe na-anọrọ na metal.

The isi mma nke electrolytic capacitors bụ ọnụnọ nke umu nke polarity, otu uru na ha jide gosiri voltaji, na mgbe ọ na-agbanwe ngwa ngwa ebibi. Nke a bụ n'ihi na chemical Filiks aa n'etiti electrolyte na metal efere. Oxide film nwayọọ nwayọọ cracks na oge izu.

Types of capacitors na ha ngwa

E nwekwara ngwaọrụ nke na-eje ozi dị ka ndị dielectric mica, ha na-eji dị iche iche nrụnye. Ebe ọ bụ na mica naanị bụ ike nke na-akpakọba ike, ndị a na ụdị capacitors nwere nnukwu capacitance na dielectric ike. The ọghọm agụnye kwa nke akwusighi, nonlinearity, elu price na na nduzi nke capacitance ugbu a.
