A plane parallel plate capacitor has air between plates and disc shaped plates of radius 3.0 mm that are coaxial and 2.5 mm apart.Charge is being accumulated on the plates of the capacitor.What is the displacement current between the plates at an instant when the time rate of charge accumulation on the plates is 1.5 $\mu$C/s?

The displacement current $I_d$ between the plates of a capacitor is equal to the rate of change of electric flux, which is directly proportional to the rate of change of charge ($\frac{dQ}{dt}$) on the plates. Given the rate of charge accumulation is $1.5 \times 10^{-6} C/s$, this value directly represents the displacement current, making the correct answer $1.5 \times 10^{-6} A$.
