Question

The number of electrons for one coulomb of charge is

• A. $6.25\times 10^{23}$
• B. $6.25\times 10^{21}$
• C. $6.25\times 10^{19}$
• D. $6.25\times 10^{18}$

Answer 1

Answer: (D)

We know that
$1e=1.6\times 10^{-19}C$
$\Rightarrow 1C=\frac{1}{1.6\times 10^{-19}}=6.25\times 10^{18}$ electrons
