Three capacitors of capacitance `3 muF, 10 muF` and `15 muF` are connected in series to a voltage source of `100 V`. The charge on `15 muF` is

A

`50 muC`

B

`100 muC`

C

`200 muC`

D

`280 muC`

Text Solution

Verified by Experts

The correct Answer is:
C
`1/(C_(eq))=1/3+1/10+1/15=(10+3+2)/30`
`C_(eq)=30/15 =2muF`
`Q=C_(eq)V=30/15 xx =200muF`
