Inductance yog los cua cov hlau mus rau hauv ib co coil.Thaum cov dej ntws tam sim no, cov hlau nplaum muaj zog yuav tsim nyob rau ntawm ob qho kawg ntawm lub kauj (inductor).Vim yog cov nyhuv ntawm electromagnetic induction, nws yuav cuam tshuam qhov kev hloov ntawm tam sim no.Yog li ntawd, cov inductance muaj ib tug me me tsis kam mus rau DC (zoo ib yam li luv luv Circuit Court) thiab ib tug siab tsis kam mus rau AC, thiab nws kuj muaj feem xyuam rau lub zaus ntawm AC teeb liab.Qhov siab dua qhov zaus ntawm AC tam sim no dhau los ntawm tib lub ntsiab lus inductive, qhov ntau dua tus nqi kuj.
Inductance yog lub zog cia khoom uas tuaj yeem hloov hluav taws xob rau hauv lub zog sib nqus thiab khaws cia, feem ntau tsuas muaj ib qho winding.Inductance originated los ntawm cov hlau-core coil siv los ntawm M. Faraday nyob rau hauv England nyob rau hauv 1831 mus nrhiav tau qhov tshwm sim ntawm electromagnetic induction.Inductance kuj tseem ua lub luag haujlwm tseem ceeb hauv hluav taws xob circuits.
Cov yam ntxwv ntawm inductance: DC kev sib txuas: yog hais txog tias nyob rau hauv DC Circuit Court, tsis muaj kev cuam tshuam ntawm DC, uas yog sib npaug rau cov xaim ncaj.Resistance rau AC: Cov kua uas thaiv AC thiab tsim ib qho impedance.Qhov ntau zaus, qhov ntau dua qhov impedance tsim los ntawm lub kauj.
Tam sim no thaiv cov nyhuv ntawm inductance kauj: tus kheej-induced electromotive quab yuam nyob rau hauv inductance kauj yog ib txwm resistant rau tam sim no hloov nyob rau hauv lub kauj.Inductive coil muaj qhov cuam tshuam ntawm AC tam sim no.Cov nyhuv thaiv yog hu ua inductive reactance XL, thiab chav tsev yog ohm.Nws kev sib raug zoo nrog inductance L thiab AC zaus f yog XL = 2nfL.Inductors tuaj yeem muab faib ua ntau zaus choke coil thiab qis zaus choke kauj.
Tuning thiab zaus xaiv: LC tuning Circuit Court tuaj yeem tsim los ntawm kev sib txuas ntawm inductance coil thiab capacitor.Ntawd yog, yog tias lub ntuj oscillation zaus f0 ntawm Circuit Court yog sib npaug rau zaus f ntawm lub teeb liab tsis yog AC, qhov inductive reactance thiab capacitive reactance ntawm lub Circuit Court kuj sib npaug, yog li lub zog electromagnetic oscillates rov qab mus rau hauv inductance thiab capacitance, uas yog resonance tshwm sim ntawm LC Circuit Court.Thaum lub sij hawm resonance, inductive reactance thiab capacitive reactance ntawm lub Circuit Court yog sib npaug thiab rov qab.Lub inductive reactance ntawm tag nrho cov tam sim no ntawm lub Circuit Court yog qhov tsawg tshaj plaws, thiab tam sim no tus nqi yog qhov loj tshaj plaws (xa mus rau AC teeb liab nrog f = "f0").Lub LC resonant Circuit Court muaj lub luag haujlwm ntawm kev xaiv qhov zaus, thiab tuaj yeem xaiv AC teeb liab nrog qee zaus f.
Inductors kuj muaj cov haujlwm ntawm kev lim dej, lim suab nrov, ruaj khov tam sim no thiab tiv thaiv kev cuam tshuam electromagnetic.
