Količina elementarnog naelektrisanja

Količina elementarnog naelektrisanja, obično se označava sa e je posebna količina naelektrisanja jednog protona, ili ekvivalentno, količina negativnog naelektrisanja koje nosi jedan elektron.^[1] Ovo je osnovna fizička konstanta. Da bi se izbegla konfuzija u vezi sa oznakom e ponekad se naziva i „elementarna količina pozitivnog naelektrisanja“. Izmerena vrednost je od oko 1,602176487 (40) × 10^-19 C, Kulona u Međunarodnom sistemu jedinica, ili vrednost 4,80320427 (10) × 10^-10 StatC u centimetar-gram-sekund CGS sistemu (engl. Centimetre gram second).^[2] Dok u sistemu atomskih jedinica, е kao jedinica naelektrisanja ima vrednost 1.

^ The symbol e has many other meanings. Somewhat confusingly, in atomic physics, e sometimes denotes the electron charge, i.e. the negative of the elementary charge. In the US, the base of the natural logarithm is often denoted e (italicized), while it is usually denoted e (roman type) in the UK and Continental Europe.
^ This is derived from the National Institute of Standards and Technology value and uncertainty, using the fact that one coulomb is exactly 7009299792458000000♠2997924580 statcoulombs. The conversion factor is ten times the numerical speed of light in metres per second.
