A 0.106-A current is charging a capacitor that has square plates 4.60 cm on each side. The plate separation is 4.00 mm. (a) Find the time rate of change of electric flux between the plates in V·m/s
(b) Find the displacement current between the plates in A

a

b

Explanation:

From the question we are told that

  The current is  

   The length of one side of the square

    The separation between the plate is  

Generally electric flux is mathematically represented as

differentiating both sides with respect to t is  

=>    

Here is the permitivity of free space with value  

=>  

=>  

Generally the displacement current between the plates in A

=>  

c) up is the direction the magnetic force is acting on the charge.
