A parallel plate capacitor has a plate separation of `2mm` and use a dielectric (whose dielecric strength is `200 kV//cm)` as an insulator. The maximum potential difference that can be applied to the terminals of the capacitor is

A

`10kV`

B

`20kV`

C

`30kV`

D

`40kV`

Text Solution

Verified by Experts

The correct Answer is:
D
Dielectric strength i.e., electric field at which insulator becomes conductor.
`V=Ed=200xx((2)/(10))=40kV`
