The equivalent capacitance between A and B is

Options

A. `2muF`
B. `3muF`
C. `5muF`
D. `0.5muF`

Answer

D

Explanation

`1muF` and `1muF` are in parallel combination
`C_(1)=1+1=2muF`
Again, `1muF and 1muF` are in parallel combination
`C_(2)=1+1=2muF`

These combination are in series
so, `" "(1)/(C)=(1)/(2)+(1)/(2)+(1)/(1)=(1+2+1)/(2)=(4)/(2)`
`(1)/(C)=2`
`rArr" C"=0.5muF`
