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 isoloko iphikisana nokutshintsha kwangoku 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 ye-oscillation yendalo ye-f0 yesekethe ilingana ne-frequency f ye-non-AC signal, i-inductive reactance kunye ne-capacitive reactance yesekethe nazo ziyalingana, ngoko ke amandla ombane ombane ajikeleza emva naphambili kwi-inductance kwaye i-capacitance, eyona nto i-resonance phenomenon yesekethe ye-LC.Ngexesha le-resonance, i-inductive reactance kunye ne-capacitive reactance yesekethe iyalingana kwaye ibuyele umva.I-inductive reactance ye-current ye-circuit iyona nto incinci, kwaye inani langoku likhulu (libhekisela kwisignali ye-AC nge-f=”f0″).I-LC resonant circuit inomsebenzi wokukhetha i-frequency, kwaye inokukhetha isignali ye-AC kunye nefrikhwensi ethile f.
Ii-inductors zikwanazo nemisebenzi yokucoca imiqondiso, ingxolo yokucoca, ukuzinzisa ngoku kunye nokucinezela ukuphazamiseka kwe-electromagnetic.
