Capacitors: Ihe Ndị Dị Mkpa Maka Elektrọnik
Capacitors bụ ihe dị mkpa na eletrọniki, a na-ejikwa ha eme ihe n'ọtụtụ sekit eletrọniki. Ọrụ ha bụ isi bụ ịchekwa ma wepụta ike eletrik. Isiokwu a ga-atụle nkọwa nke capacitors, ụdị ha, ụkpụrụ ọrụ, njirimara, na ojiji ha na ndụ kwa ụbọchị.
Ịghọta Capacitors
Kapasatọ, nke a makwaara dịka kọndenser, bụ ihe eletrọniki na-anaghị arụ ọrụ nke nwere ike ịchekwa ike n'ọhịa eletriki. Kapasatọ nwere ihe nduzi abụọ nke dielectric (insulator) kewara. Mgbe etinyere voltaji n'etiti ihe nduzi abụọ a, chaja eletrik na-agbakọta na efere ndị na-eduzi, na-emepụta oghere eletrik n'etiti ha.
Usoro bụ isi eji agbakọ capacitance (C) bụ:
\[C = \frac{Q}{V} \]
Ebe:
– \(C \) bụ ikike dị na farads (F),
– \( Q \) bụ chajị ọkụ eletrik dị na coulombs (C),
– \(V \) bụ voltaji dị na volt (V).
Ụkpụrụ Ọrụ nke Capacitor
Ụkpụrụ ọrụ nke capacitor dabere na nchekwa ike eletrik n'ime ọkụ eletrik e kere n'etiti efere abụọ na-eduzi. Mgbe etinyere voltaji, chaja dị mma na-agbakọta n'otu efere ebe chaja na-adịghị mma na nke ọzọ. Enwere ike ịhapụ ike eletrik a echekwara mgbe ọ dị mkpa, nke na-eme ka capacitor ahụ rụọ ọrụ dị ka ebe nchekwa ike nwa oge.
Ụdị Capacitors
1. Capacitors Akwụchiri Akwụchiri: Nwere capacitance akwụchiri akwụchiri nke a na-apụghị ịgbanwe. Ụfọdụ ihe atụ nke capacitors akwụchiri bụ seramiiki capacitors, electrolytic capacitors, na tantalum capacitors.
– Ike seramiiki: E ji ihe seramiiki mee ya, a na-ejikwa ya eme ihe n'ime sekit ugboro ugboro dị elu.
– Ndị na-enye ikike elektrọlik: Nwere ike dị elu na polarity ụfọdụ, a na-ejikarị ha eme ihe na sekit ike na nzacha.
– Tantalum Capacitors: Nwere ike ma nwee ike dị elu, a na-eji ya eme ihe n'ọrụ ndị chọrọ ntụkwasị obi dị elu.
2. Capacitor Na-agbanwe Agbanwe: Enwere ike ịgbanwe capacitance ya dịka ọ dị mkpa. A na-eji ya eme ihe dịka nhazi redio na mgbanwe ugboro ugboro.
3. Supercapacitors: Nwere nnukwu capacitance ma e jiri ya tụnyere capacitors nkịtị, nke a na-eji eme ihe n'ọrụ ndị chọrọ nnukwu nchekwa ike dịka nkwado ike na ụgbọ ala eletrik.
Njirimara Capacitor
– Ike (C): Ihe atụ nke ikike capacitor nwere ịchekwa chaja eletriki.
– Voltaji na-arụ ọrụ (V): Voltaji kachasị elu enwere ike itinye na capacitor n'emebighị ya.
– Ntachi obi: Mwepu nke ikike site na uru aha e gosipụtara na pasentị.
– Impedance (Z): Nguzogide dị irè nke capacitor na mgbanwe ọkụ eletrik (AC), dabere na ugboro ole.
– Ugboro Mgbanwe Onwe: Ugboro nke impedance capacitor ruru obere.
– Ike Mfu: Ike furu efu n'ụdị okpomọkụ mgbe a na-eji capacitor, nke a na-egosipụtakarị dịka ihe na-eme ka ihe gbasaa (tan δ).
Ngwa Capacitor
1. Nzacha: A na-eji capacitors eme ihe na nzacha iji mee ka voltaji dị nro na sekit ike. Dịka ọmụmaatụ, na ọkọnọ ike, capacitors na-enyere aka belata ripple voltaji.
2. Njikọta na Mkpọchi: Na sekit eletrọnịkị, a na-eji capacitors ejikọta usoro abụọ nke sekit na-enweghị nsogbu DC bias (njikọ) na iji belata nnyonye anya ugboro ugboro (ịkpọchi).
3. Nchekwa Ike: A na-eji Supercapacitors eme ihe maka nchekwa ike nwa oge, na-enye ike nkwado maka ngwaọrụ eletrọniki dịka kọmputa na ụgbọ ala eletrik.
4. Nhazi sekit: A na-eji capacitors mgbanwe eme ihe na redio iji họrọ ugboro ole a kapịrị ọnụ site na ịgbanwe capacitance nke sekit resonant.
5. Sensọ na Mmetụta: A na-eji Capacitors eme ihe na sensọ dị iche iche, dị ka sensọ aka capacitive nke e ji eme ihe na ihuenyo mmetụ aka.
6. Mmalite Moto: A na-eji capacitors mmalite eme ihe na moto eletriki iji nye ike mbụ achọrọ iji malite ntụgharị.
Mmepe nke Capacitors
Teknụzụ Capacitor na-aga n'ihu na-aga n'ihu ka ihe ọhụrụ na usoro mmepụta ka mma. Mmepe na ihe dielectric, dị ka polima ọhụrụ na seramiiki, emeela ka ikike na nkwụsi ike nke capacitors dịkwuo elu. Ọzọkwa, usoro mmepụta ọgbara ọhụrụ na-enye ohere maka obere nha capacitor nwere ikike dị elu, na-akwado obere nhazi nke ngwaọrụ eletrọnịkị.
Supercapacitors bụ ihe ọhụrụ dị mkpa na teknụzụ capacitor. Site na ikike dị elu karịa capacitors nkịtị, supercapacitors na-enye ikike nchekwa ike dị nso na nke batrị, mana ha nwere uru n'ihe gbasara ndụ na ọsọ chaja.
Uru na ọghọm nke Capacitors
Keuntungan:
– Nzaghachi Ngwa Ngwa: Capacitors nwere ike ịchekwa ma wepụta ike ngwa ngwa.
– Ogologo Ndụ: Ndụ nke capacitors, ọkachasị ụdị ndị na-abụghị electrolyte, nwere ike ịdị ogologo oge.
– Obere Ike: Arụmọrụ dị elu na nchekwa na ntọhapụ ike.
