A silver wire has resistivity ? = 1.60 × 10-8 O·m and a cross-sectional area of 4.90 mm2. The current in the wire is uniform and changing at the rate of 2150 A/s when the current is 140 A. (a) What is the magnitude of the (uniform) electric field in the wire when the current in the wire is 140 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?
A circular capacitor has a radius R = 0.200 m as shown in thefigure. The electric field between the plates is given by Ey = 1.50t^2 N/(Cs2), where the time t is in seconds.

distance r = 0.120 m from the axis of thecircular plates?
b) As a function of time, what is the magnitude of the magneticfield between the plates a
distance r = 0.240 m from the axis of thecircular plates?
c) As a function of time, what is the total displacement currentthrough the capacitor?
