Question

A parallel plate capacitor of plate separation 2 mm is connected in an electric circuit having source voltage 400 V. What is the value of the displacement current for 10^-6 second if the plate area is 60 cm²?

विकल्प

• 1.062 × 10^-2 A

• 2 × 10^-2 A

• 2.1 × 10^-4 A

• None

Answer 1

1.062 × 10^-2 A

Explanation:

According to the relation,

`"I"_"D" = epsilon_0 "EA"/"t" = epsilon_0 (("V"/"d")"A")/"t"`

`"I"_"D" = (epsilon_0 "VA")/"dt"`

`"I"_"D" = (8.82 xx 10-12 xx 400 xx (60 xx 10^-4))/(10^-6 xx 2 xx 10^-3)`

`"I"_"D" = 1.062 xx 10^-2` A
