Physics - Current Electricity Question with Solution | TestHub

A current of$5 \mathrm{A}$is passing through a non-linear magnesium wire of cross-section$0.04{ \mathrm{m}}^2$. At every point the direction of current density is at an angle of$60°$with the unit vector of area of cross-section.
The magnitude of electric field at every point of the conductor is: (resistivity of magnesium$\rho =44\times {10}^{-8} \mathrm{\Omega m}$)
