A current of $\displaystyle 1.5$ A is maintained in a copper wire of length $\displaystyle 1$ m with area of cross-section $\displaystyle 1.7 \times 10^{-7} \mathrm{~m}^{2}$. The magnitude of electric field in the wire is $\displaystyle \left[\rho_{\mathrm{Cu}}=1.7 \times 10^{-8} \Omega \mathrm{~m}\right)$
