A capacitor of 20 muF is charged to 500 ...

A capacitor of `20 muF` is charged to `500` volts and connected in parallel ith another capacitor of `10 muF` and charged to `200` volts. The common potential is

A

`200` volts

B

`300` volts

C

`400` volts

D

`500` volts

Text Solution

Verified by Experts

The correct Answer is:
C
`V = (V_(1)C_(1) + V_(2)C_(2))/(C_(1) + C_(2)) = (500 xx 20 + 200 xx 10)/(20 + 10) = 400 V`
