Nyob hauv qhov xwm txheej, emf yog tsim tawm thaum sib nqus teb hloov pauv tshwm sim los ntawm qhov chaw… induction, uas tsim ib tug voltage sib txawv ntawm lub generator terminals.
Lub zog ntawm electromotive yog dab tsi?
Kev ua haujlwm ntawm ib chav ntawm hluav taws xob, lossis lub zog uas tau txais ib chav hluav taws xob, yog lub zog hluav taws xob. Electromotive force yog tus yam ntxwv ntawm txhua lub zog muaj peev xwm tsav hluav taws xob nyob ib ncig ntawm lub voj voog.
Vim li cas electromotive quab yuam?
Electromotive force (EMF) yog qhov hluav taws xob tsim los ntawm txhua qhov chaw ntawm hluav taws xob xws li roj teeb lossis photovoltaic cell. Lo lus " quab yuam" yog me ntsis dag, vim EMF tsis yog lub zog, tab sis yog "muaj peev xwm" muab lub zog.
EMF txhais li cas?
Ib cheeb tsam ntawm hluav taws xob thiab sib nqus rog tshwm sim los ntawm hluav taws xob hluav taws xob. Cov kws tshawb fawb tab tom kawm seb EMFs los ntawm cov kab hluav taws xob, cov khoom siv hluav taws xob, thiab cov xov tooj wireless thiab xov tooj ntawm tes tuaj yeem ua rau mob qog noj ntshav lossis lwm yam teebmeem kev noj qab haus huv. Kuj hu ua electromagnetic field
piv txwv electromotive quab yuam yog dab tsi?
Electromotive quab yuam txhais tau tias yog lub zog hluav taws xob uas ua rau cov dej ntws tam sim no hauv ib lub voj voog. Ib qho piv txwv ntawm lub zog hluav taws xob yog voltage generated los ntawm lub roj teebLub zog ntawm ib chav tsev them nqi uas tau hloov pauv los ntawm tshuaj lom neeg, tshuab, lossis lwm yam khoom siv hluav taws xob rau hauv hluav taws xob hauv lub roj teeb lossis dynamo.
