Practicing Success
A parallel plate capacitor of plate separation 2 mm is connected in an electric circuit having source voltage 400V. If the plate area is 60 cm2, then the value of displacement current for 10–6 sec. will be: |
1.062 A 1.062 × 10-2 A 1.062 × 10-3 A 1.062 × 10-4 A |
1.062 × 10-4 A |
$I_{D}=\varepsilon_0 \frac{\partial \phi_{E}}{\partial t}=\varepsilon_0 \frac{EA}{t}=\frac{\varepsilon_0 VA}{dt}$ or $I_{D}=\frac{8.85 \times 10^{-12} \times 400 \times 60 \times 10^{-4}}{2 \times 10^{-3} \times 10^{-6}}$ = 1.062 × 10-4 A |
