Resistance R, inductance L, thiab capacitance C yog peb lub ntsiab lus tseem ceeb thiab tsis muaj nyob hauv ib lub voj voog, thiab txhua lub voj voog ua tsis tau yam tsis muaj peb qhov no (tsawg kawg yog ib qho ntawm lawv).Qhov laj thawj yog vim li cas lawv yog cov khoom siv thiab tsis yog vim R, L, thiab C sawv cev rau ib hom kev tivthaiv, xws li cov khoom tiv thaiv, thiab ntawm qhov tod tes, lawv sawv cev rau tus lej, xws li tus nqi tsis kam.
Nws yuav tsum tau hais tshwj xeeb ntawm no tias muaj qhov sib txawv ntawm cov khoom hauv ib lub voj voog thiab cov khoom siv lub cev tiag tiag.Lub npe hu ua Cheebtsam hauv Circuit Court tsuas yog ib qho qauv, uas tuaj yeem sawv cev rau qee yam ntawm cov khoom siv tiag tiag.Cias muab, peb siv lub cim los sawv cev rau ib tug yam ntxwv ntawm cov khoom siv tiag tiag, xws li resistors, hluav taws xob furnaces, thiab lwm yam hluav taws xob cua sov rods thiab lwm yam khoom muaj peev xwm sawv cev rau hauv circuits siv resistive Cheebtsam raws li lawv cov qauv.
Tab sis qee cov khoom siv tsis tuaj yeem sawv cev los ntawm ib qho khoom siv, xws li winding ntawm lub cev muaj zog, uas yog lub kauj.Obviously, nws tuaj yeem sawv cev los ntawm inductance, tab sis cov winding kuj muaj tus nqi tsis kam, yog li kuj yuav tsum tau siv los sawv cev tus nqi tiv thaiv no.Yog li ntawd, thaum ua qauv ib lub cev muaj zog winding nyob rau hauv ib tug Circuit Court, nws yuav tsum tau sawv cev los ntawm ib tug series ntawm inductance thiab kuj.
Kev tawm tsam yog qhov yooj yim tshaj plaws thiab paub tshaj plaws.Raws li Ohm txoj cai, tsis kam R = U / I, uas txhais tau hais tias tsis kam yog sib npaug ntawm qhov hluav taws xob faib los ntawm tam sim no.Los ntawm qhov kev xav ntawm cov units, nws yog Ω = V / A, uas txhais tau hais tias ohms yog sib npaug rau volts faib los ntawm amperes.Hauv ib lub voj voog, qhov kev tawm tsam sawv cev rau kev thaiv cov nyhuv ntawm qhov tam sim no.Qhov loj dua qhov kev tiv thaiv, qhov muaj zog ntawm kev thaiv cov nyhuv ntawm qhov tam sim no… Hauv luv luv, kev tiv thaiv tsis muaj dab tsi hais.Tom ntej no, peb yuav tham txog inductance thiab capacitance.
Qhov tseeb, inductance kuj sawv cev rau lub zog khaws cia muaj peev xwm ntawm inductance Cheebtsam, vim tias qhov muaj zog ntawm cov hlau nplaum, lub zog ntau dua nws muaj.Sib nqus teb muaj zog, vim hais tias nyob rau hauv no txoj kev, magnetic teb muaj peev xwm siv zog ntawm hlau nplaum nyob rau hauv magnetic teb thiab ua hauj lwm rau lawv.
Dab tsi yog kev sib raug zoo ntawm inductance, capacitance, thiab tsis kam?
Inductance, capacitance lawv tus kheej tsis muaj dab tsi ua nrog kev tiv thaiv, lawv cov chav nyob sib txawv kiag li, tab sis lawv txawv hauv AC circuits.
Nyob rau hauv DC resistors, inductance yog sib npaug rau luv luv Circuit Court, thaum capacitance yog sib npaug rau qhib Circuit Court (qhib Circuit Court).Tab sis nyob rau hauv AC circuits, ob qho tib si inductance thiab capacitance tsim muaj qhov sib txawv ntawm qhov sib txawv nrog cov zaus hloov.Lub sijhawm no, tus nqi tiv thaiv tsis tau hu ua qhov tsis kam, tab sis hu ua reactance, sawv cev los ntawm tsab ntawv X. Tus nqi tiv thaiv tsim los ntawm inductance yog hu ua inductance XL, thiab tus nqi tsis kam tsim los ntawm capacitance hu ua capacitance XC.
Inductive reactance thiab capacitive reactance zoo ib yam li cov resistors, thiab lawv cov units yog nyob rau hauv ohms.Yog li ntawd, lawv kuj sawv cev rau qhov thaiv cov nyhuv ntawm inductance thiab capacitance ntawm tam sim no hauv Circuit Court, tab sis qhov tsis kam hloov nrog zaus, thaum inductive reactance thiab capacitive reactance hloov nrog zaus.
