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 cm^(2)`, then the value of displacement current for `10^(-6) sec` will be

A

`1.062 A`

B

`1.062 xx 10 ^(-2) A`

C

`1. 062 xx 10 ^(-3) A`

D

`1. 062 xx 10 ^(-4) A`

Text Solution

Verified by Experts

The correct Answer is:
B
`I _(D) = epsi _(0 ) xx ( d phi _(E))/( dt )= epsi _(0) (EA)/(t) = epsi _(0) ((V)/(d)). (A)/(t)`
`= (8.85 xx 10 ^(-12) xx 400 xx 60 xx 10 ^(-4))/( 2 xx 10 ^(-3) xx 10 ^(-6))=1. 062 xx 10 ^(-2) A`
