Txawm tias nws lub npe, electromotive zog tsis yog tiag ib zog . Nws yog feem ntau ntsuas hauv units ntawm volts, sib npaug hauv meter-kilogram-thib ob system rau ib joule ib coulomb ntawm hluav taws xob.

Hais txog qhov no, EMF yog dab tsi thiab nws chav tsev?

Daim ntawv thiab units ntawm kev ntsuas Zoo li lwm yam kev ntsuas ntawm lub zog ib qho nqi, emf ua siv SI chav tsev volt, uas yog sib npaug rau ib joule ib coulomb. Electromotive quab yuam hauv electrostatic units yog statvolt (hauv centimeter gram thib ob system ntawm units sib npaug ntawm tus nqi rau ib qho erg ib electrostatic chav tsev tus nqi).

Ib sab saum toj, koj txhais li cas los ntawm electromotive quab yuam? Nws kuj tseem tuaj yeem txhais tau tias muaj peev xwm sib txawv ntawm tus nqi ntawm ob lub ntsiab lus hauv Circuit Court. Electromotive quab yuam Nws tseem hu ua voltage, thiab nws yog ntsuas nyob rau hauv volts. Electromotive quab yuam tsis yog tiag ib zog ; es, nws yog ib qho kev ntsuas ntawm lub zog ntawm ib chav tsev, tab sis lub sij hawm tseem nyob rau keeb kwm vim li cas.

Ib yam li ntawd, cov qauv ntawm electromotive quab yuam yog dab tsi?

Cov emf ua yog sib npaug rau kev ua haujlwm ntawm tus nqi them ib chav (ϵ=dWdq) thaum tsis muaj qhov ntws tam sim no. Txij li chav tsev rau kev ua haujlwm yog joule thiab chav them nqi yog coulomb, chav tsev rau emf ua yog volt (1V = 1J/C).

Dab tsi yog induced electromotive quab yuam?

Induced EMF . Ib Lub zog hluav taws xob los yog EMF yog hais tias yog induced thaum lub flux txuas nrog ib tug conductor los yog coil hloov. Qhov kev hloov pauv hauv flux no tuaj yeem tau txais ob txoj kev sib txawv; uas yog los ntawm statically los yog dynamically ua emf.
