Q=It also Q=ne [e=1.6 × 10-19 C] ∴ ne=It or n=(It/e)=(1 A × 1 s/1.6 × 10-19) =6.25 × 1018 electrons s-1

Q. $1$ ampere current is equivalent to

$6.25 \times 1 0^{18}$ electrons $s^{- 1}$

$2.25 \times 1 0^{18}$ electrons $s^{- 1}$

$6.25 \times 1 0^{14}$ electrons $s^{- 1}$

$2.25 \times 1 0^{14}$ electrons $s^{- 1}$

$Q = I t$ also $Q = n e [e = 1.6 \times 1 0^{- 19} C]$
$∴ n e = I t$ or $n = \frac{I t}{e} = \frac{1 A \times 1 s}{1.6 \times 1 0 ^{- 19}}$
$= 6.25 \times 1 0^{18}$ electrons $s^{- 1}$

Q. 1 ampere current is equivalent to

6.25×1018 electrons s−1

2.25×1018 electrons s−1

6.25×1014 electrons s−1

2.25×1014 electrons s−1
