The Story of the Electric Charge ‘e’ of the Electron
Abstract
Hoa Van Nguyen
In the mainstream of Physics, the electric charge e of the electron is considered as a universal constant. Its numerical value has been determined by the oil-drop experiment of Millikan: e = 1.602 x 10-19 C. In his Nobel lecture (1923) he said this value mainly depended on the physical conditions of the experiment: the velocity of the oil-drop and the electric field used in the experiment. So, if these physical conditions change, the measured value of e would change accordingly. In other words, the constancy of e is a mere assumption or postulate for the convenience of the research of physics.
