Question

How many electrons are there in one coulomb of electricity?

• A. $6.023\times {10}^{23}$
• B. $1.64\times {10}^{24}$
• C. $6.24\times {10}^{18}$
• D. $6.24\times {10}^{24}$

Answer 1

Answer: (C)

$6.24\times {10}^{18}$

Change on $1e^{-}=1.602\times {10}^{-19}$ $C$

If total charge $=1$ $C$

$\therefore$ Total no. of $e^{-}=\frac{1}{1.602\times {10}^{-19}}=6.24\times {10}^{18}{e}^{-}$

Hence, the correct option is $\left(C\right)$.
