Physics - Current Electricity Question with Solution | TestHub

An aluminium (Al) rod with area of cross-section $4\times 10^{-6}{\mathrm{m}}^2$ has a current of 5 ampere, flowing through it. Find the drift velocity of electron in the rod. Density of $\mathrm{Al}=2.7\times 10^3\mathrm{kg}/{\mathrm{m}}^3$ and Atomic wt. $=27$. Assume that each $\mathrm{Al}$ atom provides one electron
