Qhov tshwj xeeb zaus txiav txim siab los ntawm qhov tseem ceeb ntawm kev tiv thaiv, capacitance, thiab inductance yog hais txog resonance hauv AC circuits. Lub resonance zaus point tshwm sim qhov twg qhov inductance reactance ntawm inductor yog sib npaug rau lub capacitance reactance ntawm qhov zaus hloov.
Qhov tseem ceeb tshaj plaws hauv Circuit Court siv nyob rau hauv series resonant circuits rau hluav taws xob thiab hluav taws xob circuits muaj nyob rau hauv ntau yam ntaub ntawv xws li suab nrov lim, AC fais fab lim, thiab tshaj tawm thiab TV tuning circuits. Ib qho kev xaiv tuning Circuit Court tsim tau cov channel ntawm ntau zaus. Lub resonance ntawm ib series RLC Circuit Court tshwm sim thaum lub inductance thiab capacitance reactance yog sib npaug zos loj, tab sis tshem tawm ib leeg vim ib theem sib txawv ntawm 180 degrees.
Tam sim no series resonant circuit diagram qhia tau hais tias lub amplitude ntawm lub Circuit Court tam sim no nce los ntawm hauv qab mus rau sab saum toj thiab cov zaus nce los ntawm sab laug mus rau sab xis. Cov qauv resonant zaus qhia tau hais tias tuav xws li ib tug yooj yim series LC Circuit Court, tus kheej ncov tus nqi ntawm ib tug yooj yim parallel LC Circuit Court tuaj yeem pom ntawm qhov kev npaj zaus ntawm 157.9 Hz. Kev soj ntsuam tsis ntev los no qhia tias qhov xav tau resonant point yog 159.55 Hz.
Thaum lub hwj chim zaus mus txog resonance, tag nrho impedance ntawm series LC Circuit Court nyhav rau xoom. Vim muaj cov dej ntws tam sim no thiab ntau tus neeg tiv thaiv impedances, tus kheej cov khoom ntawm LC Circuit Court tuaj yeem tsim cov hluav taws xob siab heev thaum lub sij hawm resonance. Kev phom sij siab voltage yuav raug tsim los ntawm cov capacitors thiab inductors.
Parallel resonance
Lub resonance ntawm parallel RLC circuits yog ntau nyuaj duaseries resonance. Muaj peb txoj hauv kev los txhais cov resonant zaus, uas sib hloov mus rau tib qho kev qhia rau lub series resonant zaus nrog qis kuj nyob rau hauv Circuit Court. Nyob rau hauv ntau txoj kev, parallel resonant circuits yog zoo tib yam rau series resonant circuits vim hais tias lawv yog ob qho tib si ternary tes hauj lwm uas muaj ob lub ntsiab reactive, ua rau lawv thib ob -order circuits. Lawv tag nrho cov cuam tshuam los ntawm kev hloov pauv ntawm lub zog zaus thiab muaj qhov zaus ntawm qhov uas lawv ob lub ntsiab lus reactive tshem tawm ib leeg, yog li cuam tshuam rau cov yam ntxwv ntawm Circuit Court.
Thaum lub hwj chim zaus mus txog resonance, tag nrho impedance ntawm parallel LC Circuit Court nyhav rau infinity. Thaum tag nrho cov impedance nce mus rau infinity thiab lub capacitive thiab inductive reactance sib npaug, cov roj tank Circuit Court tsis kos tam sim no los ntawm AC fais fab mov.
Resonance nyob rau hauv Series Parallel Circuits
Nyob rau hauv yooj yim resistive los yog reactive hwj chim circuits, ntse hloov nyob rau hauv impedance yuav manifested ntawm resonant zaus.
