Question

What do we mean when we say Q=ne please explain breifly ?

Answer 1

e is the fundamental charge of a proton and of an eletron
Its value is e = 1,6 x 10⁻¹⁹ C

We say that electric charge is quantized due it only can exist as a multiple of "e"

So Q = n.e

Charge is obtained multiplying a certain number of charges (n) by the fundamental charge (e)
