Equivalent capacity between A and B is

Options

A. `2muF`
B. `3muF`
C. `4muF`
D. 0.5mu F`

Answer

D

Explanation

Equivalent capacity of `1muF and 1muF` capacitor joined in parallel `C.= 1+1=2muF`
Now, this circuit can be represented as

Now, the total capacity of circuit in series
`(1)/(C )= (1)/(2) + (1)/(1) +(1)/(2)`
`C= (1)/(2)= 0.5muF`
