Condenser `A` has a capacity of `15 muF` when it is filled with a medium of dielectric constant `15`. Another condenser `B` has a capacity `1muF` with air between the plates. Both are charged separately by a battery of `100V`. After charging, both are connected in parallel without the battery and the dielectric material being removed. The common potential now is

A

400 V

B

800 V

C

1200 V

D

1600 V

Text Solution

Verified by Experts

The correct Answer is:
B
By conservation of charge
`1500+100=2V_(f)`
`V_(f)=800V`
