Vedclass · Answer

(A) Given current $I = 0.5 \ A$ and time $t = 2 \ hours = 2 	imes 3600 \ s = 7200 \ s$. The total charge $Q$ flowing through the wire is given by $Q = I 	imes t = 0.5 \ A 	imes 7200 \ s = 3600 \ C$. The charge of one electron is $e = 1.602 	imes 10^{-19} \ C$. The number of electrons $n$ is calculated as $n = \frac{Q}{e} = \frac{3600 \ C}{1.602 	imes 10^{-19} \ C} \approx 2.247 	imes 10^{22} \approx 2.25 	imes 10^{22}$. Thus,$2.25 	imes 10^{22}$ electrons flow through the wire.

If a current of $0.5 \ A$ flows through a metallic wire for $2 \ hours$,then how many electrons would flow through the wire?
