Expert Solution
(a)What is the displacement current ?! and displacement current density ?! (current per unit of area) in the air space between the plates?
Given conduction current ic=5.0 ?
So the displacement current ?d = conduction current ic =5.0 ?
and current density J= id/A
where A=L2=82=64mm=64*10-3m
Current density J= 5/(64*10-3)=78.125 A/m2
(b) What is the rate at which the electric field between the plates is changing?
The rate at which the electric field between the plates is changing
is rate of electric field
= 78.125/ (8.854*10-12)
= 8.823**1012 A/Fm
(c) What is the value of ? ∙ ?? around the dashed path, where ? = 2.0 ?? and ? =3.0 ???
