Active kuj nyob rau hauv lub AC Circuit Court

Hluav taws xob cov Circuit Court assumes hauv lub xub ntiag nyob rau hauv nws muaj pes tsawg leeg ntawm ib tug xov tooj ntawm txawv Cheebtsam. Capacitors thiab inductance ntsiab muaj nyob rau hauv lub Circuit Court kom muab tau cov feem ntau ntau yam teebmeem. Active kuj yog li yog tam sim no nyob rau hauv daim ntawv ntawm ib tug neeg hais, resistors thiab tus kuj thaiv. Physics ntawm tej yam uas cov Circuit Court ib feem rau hauv kev cai lij choj ntawm ndlwg ntawm hluav taws xob phenomena kawm heev kom huv si, thiab tsis ntau sib txawv ntawm qhov xwm ntawm tus khiav ntawm hluav taws xob tam sim no, seb nws yuav nyob rau hauv tus ntawm AC los yog DC voltage.

Active kuj nyob rau hauv lub AC Circuit Court ua hauj lwm nyob rau hauv tib yam li nyob rau hauv lub qhov voltage hom mov. Nws yog ib heev lwm tus tshaj plaws - lub ntsiab ntawm capacitance thiab inductance. Yog hais tias lub Circuit Court feem, nyob rau lub capacitor yog kev cob cog rua, yog tsis tau kiag li DC tivthaiv, cov inductor rau nws muaj tsis ntxim. Nyob rau hauv lub khiav ntawm ncaj qha tam sim no nyob rau hauv lub embodiment nrog ib tug inductance muaj feem xyuam rau xwb cov kuj ntawm lub active coils.

Heev tej yam txawv thaum piav txog hluav taws xob dab nyob rau hauv cov saw hlau ntawm alternating tam sim no. Capacitors ua conductors, thiab ib tug inductor (zawm caj pas yog kauj ntawm lub transformer thiab thiaj li nyob.) Tau inductive reactance, thiab nws, nyob rau hauv lem, plays ib tug ntau npaum li cas ib qho tseem ceeb luag hauj lwm, thiab cov kuj yog feem ntau tsuas yog tsis coj mus rau hauv tus account.

Tab sis, cuaj kaum, qhov yuav tsum tau rau ib tug muaj tseeb muab xam los ntawm qhov yuav tsum tau coj mus rau hauv tus account qhov no kev tivthaiv. Yuav pib to taub yuav ua li cas lub active kuj ntawm lub kauj ua ke nrog ib tug inductive, nws yuav tsum nyob rau hauv general xav txog lub ntaus ntawv ib tug standard inductor.

Nyob rau hauv lub luag hauj lwm ntawm ib tug Circuit Court tivthaiv no ntaus ntawv yog tsis muaj dab tsi ntau tshaj li raws li ib tug bipolar caij ntawm ib tug ntau yam ntawm hluav taws xob, electromechanical thiab electronic systems thiab pab kiag li lawm. Lub ntsiab parameter nqi nws siv ib tug self-inductance. Li ntawd, nyob rau hauv lem, yog nyob tsuas yog nyob rau hauv lub geometric qhov ntev thiab cov ntaub ntawv ntawm siv thiab ua. Nyob rau inductance nqi tsis cuam tshuam tej nuj nqis tam sim no los yog cov voltage. Daim ntawv thov inductors yog cov ntxaij lim dej rau cov suab nrov hluav, lawv siv pub rau smoothing pulsations kauj tej zaum kuj noog lub zog uas yog dav siv nyob rau hauv lub tsim ntawm resonant circuits.

Yuav kom ntsuam xyuas tej yam kuj muaj ib tug ua hauj lwm inductor, yuav tsum tau xam ib qho alternating tam sim no Circuit Court nrog ib tug hluas caij, uas yog lub kauj inductance. Xam kom nquag plias thiab inductive reactance, nws yuav zoo li qhov uas yooj yim txoj kev uas yuav xam tag nrho cov nqi yog qhov sib ntxiv ntawm lawv tsis muaj nuj nqis.

Tab sis nrog rau cov qhov tseem ceeb no tsis yog raws li ib qho yooj yim raws li nws yuav zoo li. Twg theoretical lub hauv paus, piav qhia txog cov kev siv nyob rau hauv kev xyaum ntawm cov qauv ntawm cov summation ntawm active thiab inductive reactance.

Yuav kom nrhiav tau tag nrho cov tau tsim ib txoj cai daim duab peb sab. Ib tug yog tus ceg ntawm nws tsis kam, thiab lwm leej lwm tus - inductive. Lub hypotenuse yog sib npaug zos rau tag nrho cov tsis kam ntawm cov Circuit Court, uas txhais tau yog sib npaug zos rau cov square hauv paus ntawm qhov tawm ntawm cov plaub fab ntawm lub active thiab inductive resistances.

Suav ua kev nyob rau hauv no yav tas, dais ntau yog cov lus qhia txog cov txheej txheem uas tshwm sim nyob rau hauv lub AC Circuit Court uas nws hais yog cov kauj. Nyob rau hauv cov mis ntawm Ohm txoj Kevcai peb yuav siv tus nqi ntawm cov impedance. Raws li nws yuav tsum ntxiv tau muab sau tseg hais tias ib tug tseem ceeb kuj thaum piv nrog ib tug inductive yuav feem xyuam rau theem ua haujlwm ntawm tam sim no thiab voltage. Uas yog vim li cas rau qhov siv ntawm inductors yog lug siv tsim ntawm cov tub ntxhais, uas muab teeb meem loj zoo inductive reactance.
