Displacement Current in Parallel Plate Capacitor

A parallel plate capacitor of area A = 16 cm² and separation between the plates 10 cm, is charged by a DC current. Consider a hypothetical plane surface of area A₀ = 3.2 cm² inside the capacitor and parallel to the plates. At an instant, the current through the circuit is 6A. At the same instant the displacement current through A₀ is ________ mA.
