volt (redirected from femtovolt)

volt (V) (volt) the SI unit of electric potential or electromotive force, equal to 1 watt per ampere, or 1 joule per coulomb.

volt (vlt)

n. Abbr. V

A unit of electromotive force in the International System of Units that will produce a current of 1 ampere in a circuit that has resistance of 1 ohm.

volt (V),

n the unit of electromotive force or electrical pressure; the force necessary to cause 1 ampere of current to flow against 1 ohm of resistance. A volt is the unit that is used to measure the tendency of a charge to move from one place to another.

volt, electron (eV),

n the kinetic energy gained by an electron by falling through a potential difference of 1 volt. 1 eV is equivalent to 1.6 × 10¹² ergs; 1000 eV is referred to as 1 kilo electron volt, or keV, and 1,000,000 eV are referred to as 1 mega electron volt, or MeV.
