Current is the flow of charge per unit time, I=(q/t) ⇒ q=I t ⇒ I=1, t=1 gives q=1 unit -1 Chas (1/1.6 × 10-19)=6 × 1018 electrons approximately.

Q. Statement I SI unit of charge is coulomb, denoted by $C$ . One coulomb is the charge flowing through a wire in $1 s$ , if the current is $1 A$ .
Statement II $- 1 C$ has $6 \times 1 0^{10}$ electrons.

Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.

Both Statement I and Statement II are correct but Statement II is not the correct explanation of Statement I.

Statement I is correct but Statement II is incorrect.

Statement I is incorrect but Statement II is correct.

Current is the flow of charge per unit time, $I = \frac{q}{t}$
$\Rightarrow q = I t$
$\Rightarrow I = 1, t = 1$ gives $q = 1$ unit
$- 1$ Chas $\frac{1}{1.6 \times 1 0 ^{- 19}} = 6 \times 1 0^{18}$ electrons approximately.
