Question

what is quantization of charge?

Answer 1

quantisation of charge means net charge on any object is the integral multiple of the charge on one electron
its
q=ne
q is the net charge
n is any integer
e is the charge on an electron which is 1.6 multiply 10^-19

Answer 2

quantization of charge states that net charge on an object can be only integral multiple of e that is charge on electron.
$q = ne$
where q is net charge and e is charge on an electron.
$q = 1.6 \times {10}^{ - 19} \\ c$
and n is any integer
$n = .... (- 3)( - 2)( - 1)(0)(1)(2)(3).....$
