Umgaqo wokusebenza we-inductance

I-inductance kukujija ucingo lube kwimilo yekhoyili. Xa ukuhamba kwangoku, intsimi yamagnetic enamandla iya kwenziwa kuzo zombini iziphelo zekhoyili (inductor). Ngenxa yesiphumo sokungeniswa kwe-electromagnetic, kuya kuthintela utshintsho lwangoku. Ngoko ke, i-inductance inokumelana okuncinci kwi-DC (efana nesiphaluka esifutshane) kunye nokuchasana okuphezulu kwi-AC, kwaye ukuchasana kwayo kuhambelana nokuphindaphinda kwesignali ye-AC. Ukuphakama kwe-frequency ye-AC yangoku edlula kwinto efanayo yokufundisa, likhulu ixabiso lokumelana.

I-Inductance yinto yokugcina amandla enokuguqula amandla ombane abe ngamandla emagnethi kwaye iwagcine, ngokuqhelekileyo ngojiko olunye kuphela. I-inductance ivela kwi-iron-core coil esetyenziswa ngu-M. Faraday eNgilani kwi-1831 ukufumanisa i-phenomenon ye-electromagnetic induction. I-Inductance nayo idlala indima ebalulekileyo kwiisekethe ze-elektroniki.
Iimpawu ze-Inductance: Uxhulumaniso lwe-DC: lubhekisela kwisekethe ye-DC, akukho mpembelelo yokuthintela kwi-DC, elingana nocingo oluthe ngqo. Ukumelana ne-AC: Ulwelo oluvimba i-AC kwaye luvelise i-impedance ethile. Okukhona iphezulu i-frequency, inkulu i-impedance eyenziwa yi-coil.

Impembelelo yangoku yokuthintela i-coil inductance: i-self-induced force electromotive in the coil inductance ihlala ixhathisa utshintsho lwangoku kwikhoyili. Ikhoyili ye-inductive inefuthe lokuthintela kwi-AC yangoku. Isiphumo sokuthintela sibizwa ngokuba yi-inductive reactance XL, kwaye iyunithi ithi ohm. Ubudlelwane bayo kunye ne-inductance L kunye ne-AC frequency f yi-XL = 2nfL. Ii-inductors zinokwahlulwa ikakhulu zibe yicoil yokukrwitsha rhoqo rhoqo kunye nekhoyili yokukrwitsha rhoqo.

Ukukhethwa kunye nokukhethwa kwefrikhwensi: Isekethe yokulungisa i-LC inokusekwa ngokudityaniswa okufanayo kwe-coil inductance kunye ne-capacitor. Oko kukuthi, ukuba i-frequency oscillation yendalo ye-f0 yesekethe ilingana ne-frequency f ye-non-AC signal, i-reactance inductive kunye ne-capacitive reactance yesekethe nazo ziyalingana, ngoko ke amandla ombane we-electromagnetic oscillates abuyele emva naphambili kwi-inductance kunye ne-capacitance, okuyi-resonance phenomenon ye-LC yesekethe. Ngexesha le-resonance, i-inductive reactance kunye ne-capacitive reactance yesekethe iyalingana kwaye ibuyele umva. I-inductive reactance ye-current current ye-circuit yincinci, kwaye inani langoku likhulu (libhekisela kwi-AC signal kunye ne-f = "f0") I-LC resonant circuit inomsebenzi wokukhetha i-frequency, kwaye inokukhetha isignali ye-AC kunye ne-frequency ethile f.
Ii-inductors zikwanazo nemisebenzi yokucoca imiqondiso, ingxolo yokucoca, ukuzinzisa ngoku kunye nokucinezela ukuphazamiseka kwe-electromagnetic.
