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

=>  

where’s the list ? the question is incomplete

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
