A 0.100A current is charging a capacitor that has square plates 5.00cm on each side. The plate separation is 4.00mm. Find (a) the time rate of change of electric flux between the plates and (b) the displacement current between the plates.
I pretty much know how to get the displacement current using
I= epsilon [flux/t] I just don't know how to get the electric flux
The Attempt at a Solution
b= uI= (4pi x 10^-7)(0.100)
then flux = B x A
but it asks for rate of change. the answer given is 11.3GV x m/s
any help would be appreciated.
