The capacitance between the points `A` and `B` in the given circuit will be

A

`3.5muF`

B

`3muF`

C

`2muF`

D

`1muF`

Text Solution

Verified by Experts

The correct Answer is:
D
`C_(1)=3muF,C_(2)=C_(3)=1.5muF,C_(4)=3muF,C_(PQ)=?`
Now `C_(P)=C_(2)+C_(3)=1.5+1.5=3muF`
Now `C_(1), C_(P) and C_(4)` are in series
`1/C_(s)=1/C_(1)+1/C_(p)+1/C_(4)=1/3+1/3+1/3`
`C_(s)=C_(PQ)=1muF`
