The effective capacitance between the points X and Y is

(all capacitor are of `4muF`)

Options

A. `1muF`
B. `2muF`
C. `3muF`
D. `4muF`

Answer

D

Explanation

The equivalent circuit is a wheatstone's network.

A battery is connected between X and Y.
As `C_(1)=C_(5)=C_(4)+C_(3)=4muF`
`therefore` No charge flows through `C_(2)`.
`C_(1) and C_(2) and C_(4) and C_(3)` are in series.
`therefore`The resultant capacitance of each is `2muF`.
`therefore2muF` and `2muF` will be in parallel.
`therefore`Resultant capacitance=`4muF`.
