For section `AB` of a circuit shown in , `C_(1)=1 muF, C_(2)=2 muF, E=10 V`, and the potential difference `V_(A)-V_(B)=-10 V`. Charge on capacitor `C_(1)` is
.

A

`0muC`

B

`20//3muC`

C

`40//3muC`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(A)=(q)/(C_(1))-E-(q)/(C_(2))=V_(B) or V_(A)-V_(B)-E=q((1)/(C_(1))+(1)/(C_(2))) or q=-(40)/(3)muC`.
