A typical copper wire of household wiring has cross- sectional area $3.31\times10^{-6},\mathrm{m^{2}}$ and carries a current of $5,\mathrm{A}$. What is the drift speed of the electrons? Given, density of copper $8.95,\mathrm{gcm^{-3}}$, Avogadro's number $6.02\times10^{23},\mathrm{mol^{-1}}$, molar mass of copper $63.5,\mathrm{gm}$.
