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

e is the fundamental charge of a proton and of an eletronIts value is e = 1,6 x 10⁻¹⁹ CWe say that electric charge is quantized due it only can exist as a multiple of "e"So Q = n.eCharge is obtained multiplying a certain number of charges (n) by the fundamental charge (e)
