Muaj nuj nqi ntawm Inductors

Tam sim no -Blocking Effect: Tus kheej -induced electromotive quab yuam nyob rau hauv ib tug inductor kauj ib txwm counteracts qhov kev hloov nyob rau hauv tam sim no nyob rau hauv lub kauj. Ib qho inductor coil impedes alternating tam sim no; Qhov loj ntawm qhov impediment no yog hu ua inductive reactance (xl), ntsuas hauv ohms. Nws kev sib raug zoo nrog inductance (l) thiab alternating tam sim no zaus (f) yog xl=2πfl. Inductors tuaj yeem raug faib ua qib siab - zaus choke coils thiab qis - zaus choke coils.

Tune-Insulating and Frequency-Selective Effect: Ib qho inductor coil txuas nrog rau qhov sib npaug nrog lub capacitor tuaj yeem tsim LC resonant circuit. Ntawd yog, lub voj voog lub cev oscillation zaus (f0) yog sib npaug rau qhov zaus (f) ntawm qhov tsis yog -AC teeb liab. Yog li ntawd, qhov inductive reactance thiab capacitive reactance ntawm lub Circuit Court kuj sib npaug, ua rau lub zog electromagnetic oscillate rov qab los ntawm inductor thiab capacitor -qhov no yog qhov tshwm sim ntawm LC circuit. Ntawm resonance, qhov inductive reactance thiab capacitive reactance yog sib npaug hauv qhov loj tab sis rov qab rau hauv kev coj. Tag nrho cov tam sim no nyob rau hauv Circuit Court yog nyob rau ntawm nws yam tsawg kawg nkaus inductive reactance thiab siab tshaj plaws tam sim no (rau AC signals nrog f="f0"). Lub LC resonant Circuit Court muaj lub luag haujlwm ntawm kev xaiv ntau zaus, tso cai rau nws xaiv lub teeb liab AC ntawm qhov tshwj xeeb zaus (f).
