If the charge on an electron be $1.6 \times 10^{-19} C$, find the approximate number of electrons in $1 C$
If the charge on an electron be $1.6 \times 10^{-19} C$, find the approximate number of electrons in $1 C$
We know that $q=n e,$ therefore,
$n=\frac{q}{e}=\frac{1}{1.6 \times 10^{-19}}=6 \times 10^{18}$
