Question

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

4 : 3
3 : 4
2 : 3
3 : 2

The correct answer is: 4 : 3

$C subscript A B end subscript equals 3 plus fraction numerator 3 over denominator 3 end fraction equals 4 comma mu F$ $C subscript A C end subscript equals fraction numerator 3 over denominator 2 end fraction plus fraction numerator 3 over denominator 2 end fraction equals 3 mu F$
\ $C subscript A B end subscript colon C subscript A C end subscript equals 4 colon rightwards arrow over short leftwards arrow 3$
