(D) Given: Potential difference $V = 10 \,V$,Resistance $R = 1000 \,\Omega$,Time $t = 300 \,s$.First,calculate the current $I$ using Ohm's law: $I = \frac{V}{R} = \frac{10}{1000} = 0.01 \,A$.The total charge $Q$ flowing in time $t$ is given by $Q = I 	imes t = 0.01 	imes 300 = 3 \,C$.The number of electrons $n$ is given by the relation $Q = n 	imes e$,where $e = 1.6 	imes 10^{-19} \,C$.Therefore,$n = \frac{Q}{e} = \frac{3}{1.6 	imes 10^{-19}} = 1.875 	imes 10^{19}$ electrons.

$A$ potential difference of $10 \,V$ is applied across a conductor of $1000 \,\Omega$. The number of electrons flowing through the conductor in $300 \,s$ is ..........
