A silver wire has resistivity $=1\mathrm{.}65{10}^{-8}*m$ and a cross$-$sectional area of $7\mathrm{.}00m{m}^2.$ The current in the wire is uniform and changing at the rate of $2700\frac{A}{s}$ when the current is $160$ A $.($a$)$ What is the magnitude of the $($uniform$)$ electric field in the wire when the current in the wire is $160$ A $?($b$)$ What is the displacement current in the wire at that time? $($c$)$ What is the ratio of the magnitude of the magnetic field due to the displacement current to that due to the current at a distance $r$ from the wire?
