Ụkpụrụ ọrụ nke inductance

Inductance bụ ịgbanye waya ka ọ bụrụ ọdịdị eriri igwe. Mgbe ihe dị ugbu a na-aga, a ga-emepụta ebe ndọta siri ike na nsọtụ abụọ nke eriri igwe (inductor). N'ihi mmetụta nke induction electromagnetic, ọ ga-egbochi mgbanwe nke ugbu a. Ya mere, inductance nwere obere iguzogide DC (dị ka obere sekit) na nnukwu nguzogide AC, na nguzogide ya na-ejikọta ya na ugboro ugboro nke mgbaàmà AC. Ọnụ ọgụgụ dị elu nke AC ugbu a na-agafe n'otu ihe na-emepụta ihe, ka uru nguzogide na-abawanye.

Inductance bụ ihe nchekwa ike nke nwere ike ịtụgharị ike eletrik ka ọ bụrụ ike magnetik wee chekwaa ya, na-enwekarị naanị otu ikuku. Inductance sitere na eriri igwe-isi nke M. Faraday ji mee ihe na England na 1831 iji chọpụta ihe dị n'ime induction electromagnetic. Inductance na-arụkwa ọrụ dị mkpa na sekit eletrọnịkị.
Njirimara inductance: Njikọ DC: na-ezo aka na nke dị na sekit DC, enweghị mmetụta mgbochi na DC, nke kwekọrọ na waya kwụ ọtọ. Nguzogide AC: Mmiri nke na-egbochi AC ma na-emepụta ihe mgbochi. Ka ọ na-adịwanye elu, na-ebuwanye ihe mgbochi nke eriri igwe na-emepụta.

Mmetụta mgbochi ugbu a nke eriri inductance: ike electromotive nke na-ebute onwe ya na eriri inductance na-eguzogide mgbe niile na mgbanwe dị ugbu a na eriri igwe. Igwe mmiri na-emepụta ihe nwere mmetụta mgbochi na AC ugbu a. A na-akpọ mmetụta mgbochi inductive reactance XL, na unit bụ ohm. Mmekọrịta ya na inductance L na AC ugboro f bụ XL = 2nfL. Enwere ike kewaa inductors ka ọ bụrụ eriri mkpọkọ ugboro ugboro na eriri mkpọkọ dị ala.

Ntugharị na nhọrọ ugboro: Enwere ike ịmepụta sekit nlegharị anya LC site na njikọ yiri nke eriri inductance na capacitor. Ya bụ, ma ọ bụrụ na eke oscillation ugboro f0 nke sekit bụ hà ugboro f nke na-abụghị AC mgbaàmà, na inductive reactance na capacitive reactance nke sekit bụkwa hà nhata, ya mere, ike electromagnetic oscillates azụ na pụta na inductance na capacitance, nke bụ resonance onu nke LC circuit. N'oge resonance, ndị inductive reactance na capacitive reactance nke sekit bụ Ẹkot na agbara. The inductive reactance nke ngụkọta ugbu a nke sekit bụ kacha nta, na nke ugbu a ego bụ nke kasị ukwuu (na-ezo aka AC mgbaàmà na f =”f0″) The LC resonant circuit nwere ọrụ nke na-ahọpụta ugboro, na ike họrọ AC mgbaàmà na a ụfọdụ ugboro f.
Inductor nwekwara ọrụ nke nzacha akara, nzacha mkpọtụ, mee ka ọ dị ugbu a guzosie ike na igbochi nnyonye anya electromagnetic.
