Yuav ua li cas yog lub electromotive quab yuam

Nyob rau hauv no tsab xov xwm uas peb yuav tham txog dab tsi yog qhov electromotive quab yuam hwj chim qhov twg los thiab dab tsi yog nws kev sib raug zoo nrog rau lwm cov ciaj ciam ntawm lub Circuit Court. Cia li nco ntsoov, txawm lub fact tias nyob rau hauv lub neej txhua hnub peb yuav ntse siv hluav taws xob khoom siv, muaj ntau yam kev cai tau raug muab tau los empirically thiab npaum li cas rau kev tso. Qhov no yog ib tug ntawm cov yog vim li cas rau ntev li complexity txhais cov ntsiab lus. Tu siab, txawm lub electromotive quab yuam, hais tias lub hauv paus ntawm hluav taws xob engineering, yog illuminated nyob rau hauv xws li ib tug txoj kev uas ib tug neeg uas yog tsis paub nrog hluav taws xob, yuav to taub ib yam dab tsi nyuaj heev. Peb piav qhia txog qhov teeb meem nrog kev pab los ntawm meej cov ntsiab lus uas txhua tus, thiab cov piv txwv.

Directional zog ntawm them hais nyob rau hauv ib tug neeg xyuas pib yog hu ua tus "fais tam sim no". Raws li koj paub, tag nrho cov khoom ntawm peb cov ntaub ntawv uas lub ntiaj teb no muaj li ntawm atoms. Rau lub hom phiaj ntawm clarity peb tau tias hais tias txhua atom yog sawv cev nyob rau hauv daim ntawv ntawm cov txo lab ntawm cov sij hawm ib tug qauv ntawm cov hnub ci system: nyob rau hauv qhov chaw cov tub ntxhais, thiab nyias nyob nyias ib deb ntawm nws nyob rau hauv yeej orbits ntawm lub electrons tig.

Los ntawm tej yam sab nraud cuam tshuam nyob rau hauv ib tug neeg xyuas pib txoj kev ua ib kaw Circuit Court, electromotive dag zog yuam yog generated thiab muaj ib tug hluav taws xob tam sim no. Impact "knocks tawm" valence electrons los ntawm lawv cov orbits nyob rau hauv atoms li ua dawb electrons thiab zoo them ions.

Electromotive quab yuam yog tsim nyog los "quab yuam" ntawd kom ceev mus los ntawm tus neeg xyuas pib thiab lub Circuit Court hais nyob rau hauv ib tug tej yam kev taw qhia. Yog tsis muaj nws, tam sim no yuav luag tam sim ntawd extinguished. Tsi tawm dab tsi yog qhov electromotive quab yuam, yuav tso cai rau cov kev sib piv ntawm hluav taws xob thiab dej. Ncaj yeeb nkab seem - qhov no neeg xyuas pib. Nws ob tog nws mus rau hauv cov dej lub cev. Raws li ntev raws li cov dej theem nyob rau hauv lub reservoirs yog muaj sib npaug thiab tsis muaj sib txawv, cov kua nyob rau hauv cov yeeb nkab yog nyob ruaj ruaj.

Obviously, rau tau nws tau tsiv mus nyob rau hauv peb txoj kev: los ua ib tug qhov siab qhov sib txawv (tsis ncaj ncees los yog tus nqi ntawm cov dej nyob rau hauv lub reservoirs) los yog quab yuam twj tso kua mis. Ib qho tseem ceeb point: yog hais tias peb tham txog ntsug nco (tej zaum sib txawv), uas txhais tau tias cov kev nyuaj siab. Rau EMF tib zog "yuam" vim hais tias sab nraum rog rau, nonpotential.

Tej qhov chaw ntawm hluav taws xob tam sim no muaj EMF - tib yam dag zog yuam uas txhawb lub zog ntawm them hais (nyob rau hauv cov nram no analogy rog tsiv mus nyob dej). Ntsuas nyob rau hauv volts. Lub npe hais lus rau nws tus kheej: EMF characterizes lub chaw ua hauj lwm uas txuas mus rau ib feem ntawm cov saw ntawm sab nraud rog uas ua lub xaav ntawm txhua chav tsev xwb los ntawm ib tug ncej mus rau lwm lub (nruab nrab ntawm terminals). Nws yog txaus sib npaug zos rau cov piv ntawm cov chaw ua hauj lwm ntawm sab nraud rog uas txuas mus rau tus nqi ntawm cov rooj noj xwb.

Kov xav tau emf qhov yuav muab tau los ntawm cov kev cai lij choj ntawm kev txuag ntawm lub zog thiab lub zog ntawm neeg xyuas pib. Nyob rau hauv lub kaw Circuit Court ua hauj lwm teb rau lub zog ntawm cov nqi yog pes tsawg. Txawm li cas los, tus neeg xyuas pib yog rhuab (thiab muaj zog loj tam sim no kis tau los ntawm nws ib chav tsev lub sij hawm). Xaus: Lub Circuit Court yuav tsum tau tam sim no lub kev faib ua feem ntawm lwm lub zog. Hais tias sab nraum rog - qhov no magnetic teb generators, qhov exciting electrons tsis tu ncua; lub zog ntawm tshuaj nyob rau hauv cov roj teeb.

Lub electromotive quab yuam ntawm induction twb xub cai experimentally nyob rau hauv 1831 los ntawm physicist Faraday. Nws pom hais tias cov neeg xyuas pib-permeate kab siv alternating magnetic teb, ib tug hluav taws xob tam sim no. Raug teb ceeb toom ntawm lub txheej electrons nyob rau hauv lub atoms ntawm cov uas ploj lawm lub zog rau lawv, ua rau lawv mus ua txhaum tam sim ntawd thiab pib tsiv mus (tam sim no tsev). Ntawm cov hoob kawm, qhov ncaj zog ntawm tus hais tsis muaj nyob (yuav tsis nco qab lub Relativity ntawm hluav taws xob axioms). Es, muaj ib tug pauv hais ntawm qhov ze atoms.

Tsim los ntawm lub electromotive quab yuam - nws yog ib tug nrog cov yam ntxwv ntawm tej hwj chim qhov twg los.
