Four capacitors of each of capacity `3 muF` are connected as shown in the adjoining figure. The ratio of equivalent capacitance between `A` and `B` and between `A` and `C` will be

A

`4:3`

B

`3:4`

C

`2:3`

D

`3:2`

Verified by Experts

The correct Answer is:

A

`C_(AB) = C+C/3 =(4C)/3`
`C_(AC) =C/2 +C/2 =C`
`(C_(AB))/(C_(AC))=(4C)/3 xx1/C = 4/3`
