Yuav ua li cas xam tus nqi inductance ntawm lub kauj inductor?

Inductance yog lub npe muab rau cov cuab yeej ntawm ib feem uas tawm tsam qhov kev hloov pauv tam sim no ntws los ntawm nws thiab txawm tias ib qho ncaj ntawm cov hlau yuav muaj qee qhov inductance.

Lub inductance ntawm lub kauj yog hais txog cov cuab yeej hluav taws xob uas inductive coil yuav tsum tawm tsam txhua qhov kev hloov pauv ntawm qhov tam sim no ntws los ntawm nws. Nws thiaj li ua raws li qhov inductance tsuas yog tam sim no nyob rau hauv hluav taws xob Circuit Court thaum tam sim no hloov.

Inductors tsim ib tus kheej-induced emf nyob rau hauv lawv tus kheej vim lawv hloov magnetic teb. Nyob rau hauv ib qho hluav taws xob Circuit Court, thaum lub emf yog induced nyob rau hauv tib lub Circuit Court uas tam sim no hloov cov nyhuv no yog hu ua Self-induction, (L) tab sis nws yog feem ntau hu ua back-emf raws li nws polarity yog nyob rau hauv lub opposite direction mus rau lub siv voltage.

Thaum lub emf yog induced mus rau hauv ib qho chaw nyob ib puag ncig nyob rau hauv tib lub magnetic teb, emf yog hais tias yuav induced los ntawm Mutual-induction, (M) thiab kev sib nrig sib induction yog lub hauv paus kev khiav hauj lwm thawj coj ntawm transformers, motors, relays thiab lwm yam. Nws tus kheej inductance yog. Ib qho tshwj xeeb ntawm kev sib nrig sib inductance, thiab vim tias nws yog tsim nyob rau hauv ib qho kev sib cais peb feem ntau hu ua tus kheej inductance yooj yim, Inductance.

Lub hauv paus ntawm kev ntsuas rau inductance yog hu ua Henry, (H ) tom qab Joseph Henry, tab sis nws kuj muaj cov chav nyob ntawm Webers per Ampere ( 1 H=1 Wb/A ).

Lenz txoj cai qhia peb tias qhov induced emf generates ib tug tam sim no nyob rau hauv ib tug kev taw qhia uas tawm tsam qhov kev hloov nyob rau hauv flux uas ua rau lub emf nyob rau hauv thawj qhov chaw, tus thawj coj ntawm kev txiav txim thiab cov tshuaj tiv thaiv. Tom qab ntawd peb tuaj yeem txhais tau tias Inductance yog qhov tseeb: "ib lub kauj yuav muaj tus nqi inductance ntawm ib Henry thaum ib qho emf ntawm ib lub volt yog induced nyob rau hauv lub kauj yog tam sim no ntws los ntawm lub coil hloov ntawm tus nqi ntawm ib ampere / thib ob".

Hauv lwm lo lus, ib lub kauj muaj ib qho inductance, (L) ntawm ib Henry, (1H) thaum tam sim no ntws los ntawm lub kauj hloov ntawm tus nqi ntawm ib ampere / thib ob, (A / s). Qhov kev hloov no induces ib tug voltage ntawm ib volt, (VL) nyob rau hauv nws. Yog li tus lej sawv cev ntawm tus nqi ntawm kev hloov pauv tam sim no los ntawm lub qhov txhab coil hauv ib lub sijhawm yog muab raws li:

Qhov twg: di yog qhov hloov pauv tam sim no hauv Amperes thiab dt yog lub sijhawm siv rau qhov tam sim no hloov pauv hauv vib nas this. Tom qab ntawd qhov voltage induced nyob rau hauv ib lub kauj, (VL) nrog ib tug inductance ntawm LHenries raws li qhov tshwm sim ntawm qhov kev hloov nyob rau hauv tam sim no yog qhia raws li:

Nco ntsoov tias cov cim tsis zoo qhia tau hais tias qhov hluav taws xob cuam tshuam tawm tsam qhov kev hloov pauv tam sim no los ntawm lub kauj ib lub sijhawm ( di / dt ).

Los ntawm cov kab zauv saum toj no, qhov inductance ntawm lub kauj tuaj yeem raug nthuav tawm raws li:

Inductance ntawm Coil

Qhov twg: L yog qhov inductance hauv Henries, VL yog qhov hluav taws xob hla lub kauj thiab di / dt yog tus nqi hloov pauv tam sim no hauv Amperes ib ob, A / s.

Inductance, L yog qhov tseeb qhov ntsuas ntawm ib qho inductors "tsis kam" rau qhov kev hloov pauv ntawm qhov tam sim no ntws los ntawm lub voj voog thiab qhov loj dua yog nws cov nqi hauv Henries, qhov qis dua yuav yog tus nqi hloov tam sim no.
