A parallel plate capacitor consists of two circular plates of radius $ R=0.1 \mathrm{~m} $. They are separated by a short distance. If electric field between the capacitor plates changes as $ \frac{d E}{d t}=6 \times 10^{13} \frac{\mathrm{~V}}{\mathrm{~m} \times \mathrm{s}} $, then the value of displacement current is
