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 . In the SI system of units, the value of the elementary charge is exactly defined as = 1 ...
基本電荷 （符號： ，也稱 元電荷 ），是一個 質子 所帶的 電荷 量，或一個 電子 所帶的負電荷的量。. 為了避免其符號造成混淆， 有時候會被稱為 基本正電荷 （ elementary positive charge ）。. 它是一個基本 物理常數 ，是 原子單位 和一些其它 自然單位制 中的 ...
기본 전하 (基本電荷, 영어: elementary charge )는 양성자 하나가 지니고 있는 전하 이며, 또한 전자 하나가 지니고 있는 전하의 절댓값이다. 일반적으로 기호 e 를 사용하여 표현되며, 간혹 q 로 표현한다. 기본 전하는 기본적인 물리 상수 의 하나로, 원자 단위계 ...
29 mar 2009 · Electric charge is a characteristic of some subatomic particles. It is quantized in that, when expressed in units of the so-called elementary charge e, it takes integer or fractional values. Electrons by convention have a charge of −1, while protons have the opposite charge of +1. Quarks have a fractional charge of − or +.
Charge élémentaire. En physique, la charge élémentaire est la charge électrique d'un proton ou, de façon équivalente, l'opposé de la charge électrique d'un électron. Elle est notée e et s'exprime en coulombs ( C ), ou en A s dans le Système international d'unités. Elle a été mesurée pour la première fois en 1909 par le ...
La costante di struttura fine, o costante di Sommerfeld, indicata con la lettera greca αe, è la costante di accoppiamento dell' interazione elettromagnetica, di cui esprime l'intensità relativamente alla carica elementare . Fu introdotta da Arnold Sommerfeld nel 1916 come misura della deviazione relativistica delle linee spettrali del ...
