According to principle of quantization ‘ the charge on the body cannot have an arbitrary value, but its total charge is always an integral multiple of the certain minimum charge e .’ Thus if Q is charge on the body its value can be

Q = +/- ne

Quantization implies that ‘n’ can’t be a rational number. For physical and chemical properties of individual atoms quantization is used. But is ignored in case of electrically charged bodies and current carrying conductors that involve large scale transfer of electric charge. This is done because the magnitude of charge on electron is negligibly small as compared to magnitude of charge on a macroscopic body.Hence, Quantisation of charge is not applicable for macroscopic bodies
