Find the effective capacity of the combination shown below :

Explanation

Effective capacity of the three `2muF` capacitors in parallel is `2+2+2=6muF`
Effective capacity of `2muF and 6muF` in series is `=(2 xx 6)/(8) =1.5muF`
Effetive capacity of two `2muF` in series is `=(2 xx 2)/(2+2)=1muF`
`1.5muF and 1muF` are in parallel. Hence effective capacity `=1.5+1=2.5muF`
