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.

A carga elementar é aquela carga elétrica transportada por um único próton ou, de maneira equivalente em módulo, por um único elétron. Ela é exatamente 1,602 176 634 × 10 -19 C [ 1] e, convencionalmente se utiliza as letras e ou qe para denotá-la.
Definition. The SI defines the coulomb by taking the value of the elementary charge e to be 1.602 176 634 × 10−19 C, [7] but was previously defined in terms of the force between two wires. The coulomb was originally defined, using the latter definition of the ampere, as 1 A × 1 s. [8] .
A carga do elétron é exatamente -1,602 176 634 × 10 −19 C, [ 1] que é o mesmo valor da carga do próton, porém de sinal contrário. Essa diferença de sinais (negativo para os elétrons e positivo para os prótons) é apenas uma convenção que serve para indicar que possuem cargas (apesar de numericamente iguais) de natureza ...
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.
