Vim li cas V Capitalized hauv kV?

Muaj cov cai meej rau kev sau cov cim hauv lub cev thiab International System of Units (SI). Lub "V" hauv "kV" (kilovolts) yog peev rau cov laj thawj hauv qab no:

Lub Tsev yog muab los ntawm ib tug neeg lub npe

Chav tsev ntawm voltage, lub volt, muaj npe nyob rau hauv kev hwm ntawm Italian physicist Alessandro Volta.

Naming Cov Cai ntawm International System of Units

Raws li International System of Units, yog tias lub npe ntawm chav tsev tau muab los ntawm tus kws tshawb fawb lub npe, thawj tsab ntawv ntawm chav tsev lub cim yuav tsum tau sau npe. Piv txwv li:

Volt → V

Watt → W

Ampere → A

Zaus → Hz

Qhov txawv ntawm Prefixes

"Kilovolt" (kV) yog tsim los ntawm prefix "k" (lub ntsiab lus txhiab) thiab lub cim "V" (volt).

Lub prefix "k" sawv cev rau qhov tseem ceeb ntawm ib txhiab thiab yuav tsum tau sau ua tus lej qis, tsis hais lub tsev nws ua ntej. (Piv txwv li, "k" hauv km, kg, thiab kV yog tus lej qis, thaum "M" rau lab yog tus lej loj.)

Lub cim "V" sawv cev rau lub volt thiab, vim hais tias nws yog muab los ntawm ib tug neeg lub npe, yuav tsum tau capitalized.
