Consider a parallel plate capacitor of `10 muF` with air filled in the gap between the plates. Now one half of the space between the plates is filled with a dielectric of dielectric constant `4`, as shown in the figure. The capacity of the capacitor charges to

A

`25 muF`

B

`20 muF`

C

`40 muF`

D

`5 muF`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_(eq) = C_1+C_2=(A/2epsilon_0k)/d+(A/2epsilon_0)/d`
`=(Aepsilon_0)/(2d)(k+1) =10/2xx5 =25muF`
