Question:

A dielectric of permittivity 3.5 x l0-l1 F/m completely fills the volume between two capacitor plates. For t > 0 the electric flux through the dielectric is {8.0 x 103 V· m/s3) t3. The dielectric is ideal and nonmagnetic; the conduction current in the dielectric is zero. At what time does the displacement current in the dielectric equal 21 µA?
