A parallel plate capacitor of area A = 16 cm^2 and separation between the plates 10 cm, is charged by a DC current. Consider a hypothetical plane surface of area A0 = 3.2 cm^2 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. (JEE-2025)
