Homework Statement


Quantisation means charge always exist in integral multiples of magnitude of charge of electron and to put it mathematically we say q = ne, where n is an integer 1,2,3,4 ... -1,-2,-3,... etc. Numerous print and web materials say that charge cannot exist in fraction or decimal, i.e, 2.3e, 4.6e etc. Agreed.

Homework Equations




The Attempt at a Solution


The value of e is 1.6*10^-19 C which itself contradicts the statement that no fraction or decimals is possible while dealing with charge. Also if we take n = 2, we get q = 3.2*10^-19, n =3 means q = 4.8 *10^-19 which are all fractions. Can experts throw light on this aspect? Thanks in advance

It means charge exists in multiples of integers. An easy way to put it is if you divide the value of a charge by 1.6*10^-19, you'll always get an integer and never a fraction.
