A parallel plate capacitor with air between the plates, has capacitance `3muF`. If the capacitor is immersed in a liquid of ielectric constant `4.0`, then its capacitance will be

A

`0.75muF`

B

`1.5muF`

C

`6muF`

D

`12muF`

Text Solution

Verified by Experts

The correct Answer is:
D
When a dielectric medium is inserted between plates of capacitor, the capacity of capacitor increased by K times,
i.e. `C_("new")="KC"_(0)=4xx3=12muF`
