Cov yam ntxwv tseem ceeb ntawm tus inductor yog nws qhov kev tawm tsam rau kev hloov pauv tam sim no. Thaum tam sim no ntws los ntawm ib tug inductor, ib tug magnetic teb yog generated; Raws li tam sim no kev hloov pauv, cov hlau nplaum sib nqus hloov pauv raws li, ua rau lub txee -electromotive force (rov qab-EMF) uas tiv thaiv cov kev hloov tam sim no. Yog li ntawd, ib qho inductor ua tau zoo raws li qhov luv luv hauv DC Circuit Court (muab qhov tsis txaus ntseeg thaum nyob ruaj khov- lub xeev tau mus txog), hos nyob rau hauv AC Circuit Court, nws nthuav tawm impedance uas nce nrog zaus.
Inductors muaj peev xwm khaws cia thiab tso tawm lub zog. Raws li tam sim no nce, lub inductor hloov hluav taws xob hluav taws xob rau hauv lub zog sib nqus; Raws li tam sim no ntog, nws tso tawm lub zog sib nqus rov qab rau hauv lub voj voog. Qhov "zog buffering" muaj peev xwm ua rau inductors tseem ceeb hauv cov ntawv thov xws li hloov cov khoom siv hluav taws xob, tam sim no smoothing, thiab lim circuits.
Cov inductors kuj nthuav tawm cov zaus dependence thiab cov yam ntxwv tshwj xeeb theem. Hauv AC circuits, qhov hluav taws xob hla ib qho inductor coj tam sim no los ntawm kwv yees li 90 degrees-ib theem kev sib raug zoo uas yog qhov tseem ceeb hauv cov hluav taws xob hluav taws xob thiab cov teeb liab ua haujlwm. Tsis tas li ntawd, inductor kev ua tau zoo yog cuam tshuam los ntawm cov ntaub ntawv tseem ceeb thiab lub cev qauv; inductance qhov tseem ceeb yuav txawv me ntsis nrog kev hloov pauv tam sim no, kub, thiab zaus- cov yam ntxwv uas yuav tsum tau ua tib zoo txiav txim siab thaum lub sij hawm tsim hluav taws xob.
