Tus qauv ntsuas hluav taws xob (E-field) lub zog yog qhov volt ib 'meter' ( V / m ). Lub volt ib meter, los yog ib co fractional unit raws li nws, yog siv raws li ib tug txhais tau tias ntawm kev qhia qhov siv ntawm electromagnetic teb (EM field) tsim los ntawm lub xov tooj cua transmitter.

Ua li no, VM txhais li cas slang?

VM txhais tau tias "Voice Mail" Yog li tam sim no koj paub - VM txhais tau tias "Voice Mail" - tsis txhob ua tsaug rau peb. YW! VM txhais li cas ? VM yog ib tug acronym, abbreviation los yog lus lo lus uas tau piav saum toj no qhov twg VM txhais yog muab.

Puas yog volts ib meter tib yam li Newtons rau Coulomb? Hloov newton / coulomb [N/C] hluav taws xob / meter [V/ m ] A Newton per coulomb (N/C) yog SI muab tau los ntawm lub zog ntawm hluav taws xob teb. Lub zog ntawm 1 N / C yog ua tiav yog tias a hluav taws xob ntawm 1 V yog siv los ntawm ob lub dav hlau uas tsis muaj qhov sib npaug sib npaug 1 m sib nrug.

Tseem yuav paub yog, V m zoo ib yam li N C?

Tab sis ib tug "Joule per Coulomb" (J / C ) kuj tseem hu ua volt ( V ), thiab lub peev xwm hluav taws xob yog li feem ntau hu ua qhov voltage. Yog li ntawd, hluav taws xob teb kuj tuaj yeem hais nyob rau hauv units ntawm volts ib 'meter', txij li thaum V / m = N / C . Li no ib tug electron volt sib npaug 1.602E-19 J.

Qhov twg hauv qab no muaj chav ntsuas Volt los ntawm Metre?

Lub cev muaj nuj nqis uas nws chav tsev SI yog VOLT PER METER yog " hluav taws xob teb " Ib qho E teb ntawm 1 V / m yog sawv cev los ntawm qhov sib txawv ntawm 1 Volt uas twb muaj lawm ntawm ob lub ntsiab lus uas yog 1 m sib nrug. Thiab nws cov vector kom muaj nuj nqis.
