The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.

Electrons have an electric charge of −1.602 176 634 × 10 −19 coulombs, which is used as a standard unit of charge for subatomic particles, and is also called the elementary charge. Within the limits of experimental accuracy, the electron charge is identical to the charge of a proton, but with the opposite sign. [80]
Il termine carica elementare si riferisce al quanto di carica elettrica. Viene indicata con [1] ed espressa in valore assoluto. Secondo il sistema internazionale dal 2019 il suo valore definisce l'unità di misura del coulomb ed è pari a: [2] La carica elementare corrisponde alla carica del protone (positiva) e a quella dell ...
La carica elettrica è la carica fisica responsabile dell'interazione elettromagnetica e sorgente del campo elettromagnetico. La sua unità di misura nel Sistema internazionale è il coulomb. È una grandezza scalare, dotata di segno e quantizzata, ossia può assumere solo valori multipli di una quantità elementare che corrisponde ...
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). It is equal to the electric charge delivered by a 1 ampere current in 1 second and is defined in terms of the elementary charge e, at about 6.241 509 × 10 18 e.
The elementary charge (the electric charge of the proton) is defined as a fundamental constant in the SI. The value for elementary charge, when expressed in SI units, is exactly 1.602 176 634 × 10 −19 C.
The elementary charge is the smallest electric charge found in a stable particle. A coulomb is equal to 6,241,509,629,152,650,000 elementary charges. The coulomb was named in honor of Charles-Augustin de Coulomb who worked on understanding electric charge in the late 1700s.
