Physics - Current Electricity Question with Solution | TestHub

A current of $5\mathrm{A}$ is passing through a metallic wire of cross-sectional area $4\times 10^{-6}{\mathrm{m}}^2$. If the density of the charge carriers in the wire is $5\times$ $10^{26}{\mathrm{m}}^{-3}$, the drift speed of the electrons will be $\left[\mathrm{e}=1.602\times 10^{-19}\mathrm{C}\right]$
