A parallel plate capacitor of plate separation 2 mm is connected in an electric circuit having source voltage 400 V. if the plate area is 60 cm2, then the value of displacement current for 106sec  will be

a
1.062 amp
b
1.062×10−2amp
c
1.062×10−3amp
d
1.062×10−4amp

detailed solution

Correct option is B

ID=ε0dφEdt=ε0EAt=ε0Vd.At. =8.85×10−12×400×60×10−42×10−3×10−6=1.602×10−2amp
