Question

The charge possessed by an electron is 1.6x 10-19c. find the number of electrons that will flow per second to constitute a current of 1 ampere.

Answer 1

we know that the charge of an electron is
$1.6 \times 10 {?}^{ - 19}$
then,
$1 \div 1.6 \times 10 {}^{ - 19} \times 1 \\ 10^{19} \div 1.6 \\ 10 \div 1.6 \times 10 {}^{18} \\ 6.2 \times 10 {}^{18}$
