Elementary charge

The elementary charge is, in Physique, the electric Charge of a Proton or, in an equivalent way, the opposite of the electric charge of a electron. It is noted e.

Value

The value of the elementary charge is equal to:

e = 1,602 \ 176 \ 487 \ times 10^ {- 19} C.

The relative Erreur on this value is of 8,5×10-8.

The Constante of Faraday is defined like the product of the elementary charge by the Nombre of Avogadro.

Smaller loads

Since its first measurement by Robert Millikan in 1909, the elementary charge is regarded as indivisible.

The Quark S, whose existence was postulated as of the years 1960, are supposed to have a fractional electric charge (multiples of \ frac {E} {3} ) but are confined inside Hadron S, particles whose load is a multiple of the elementary charge, and for the moment were never detected separately.
