Question

Calculate the number of electrons constitute one coulomb of charge.

Answer 1

$q=ne$

where, $q\to$ Change $,n\to$no. of $e^{-}$

$e\to$ Change on $e^{-}$

$\Rightarrow 1c=n(1.6\times {10}^{-19})$

$\Rightarrow n=\frac{{10}^{19}}{1.6}$

$\Rightarrow n={625.10}^{16}$ electrons

Hence, the answer is ${625.10}^{16}$ electrons.
