In pheesics, the electron volt (seembol eV; an aa written electronvolt[1][2]) is a unit o energy equal tae approximately 6981160000000000000♠1.6×10−19 joule (seembol J). By definition, it is the amount of energy gained by the charge of a single electron moved across an electric potential difference of one volt. By defineetion, it is the amoont o energy gained (or lost) bi the charge o a single electron moved across an electric potential difference o ane volt.

Alternatively, an electronvolt is equal to the kinetic energy acquired by an electron when it is accelerated through a potential difference of one volt. Hence, one electron volt is equal to elementary charge ( 1.60217657 × 10 -19 coulombs (C)) multiplied by one volt.

Chad Weber – [email protected], Support Universe Today podcasts with Fraser Cain, The Guide to Space is a series of space and astronomy poddcasts by Fraser Cain, publisher of Universe Today, Episode 694: Interview: Fred Watson, Australia's Astronomer at Large. Specialized electron synchrotrons, such as the Advanced Photon Source at Argonne National Laboratory. An electron-volt (eV) is the work required to move an electron through a potential difference of one volt.

Now a volt is a joule per coulomb, so an electron volt is one electric charge times one, or approx 1.6 x 10-19 joules (J). … (GeV, or billion eV), or teraelectron volts (TeV, or trillion eV). Alternatively, an electronvolt is equal to the kinetic energy acquired by an electron when it is accelerated through a potential difference of one volt. The electron volt is a unit of energy suited to energies involved in atomic studies.

The electron-volt is a unit of energy or work. When measuring a quantity, the units we use are just as important as the obtained numerical value. https://www.youtube.com/playlist?list=PLbJ42wpShvmkjd428BcHcCEVWOjv7cJ1G, Weekly email newsletter: Electron volt definition is - a unit of energy equal to the energy gained by an electron in passing from a point of low potential to a point one volt higher in potential : 1.60 × 10—19 joule. https://www.universetoday.com/newsletter, Weekly Space Hangout: An electron volt is one electron times one volt; concatenating the two together is like expressing electrical energy in "kilowatthours" or torque in "Newtonmeters" or workforce in "manyears". So, for example, the mass of the proton is 0.938 GeV/c2, which makes the GeV/c2 a very convenient unit (= 1.783 x 10-27 kg).
