Question

Number of electrons in one coulomb of charge will be

• A. $5.46\times {10}^{29}$
• B. $6.25\times {10}^{18}$
• C. $1.6\times {10}^{+19}$
• D. $9\times {10}^{11}$

Answer 1

The correct option is B $6.25\times {10}^{18}$

$n=\frac{Q}{e}=\frac{1}{1.6\times {10}^{-19}}=6.25\times {10}^{18}$
