The equivalent capactiance between `A` and `B` in the figure is `1 muF`. Then the value of capacitance `C` is

Options

A. `1.4 muF`
B. `2.5 muF`
C. `3.5 muF`
D. `1.2 muF`

Answer

A

Explanation

From the given figure, total capacitance is
`(1)/(1) = (1)/(C ) + (1)/((1 + 2.5)) rArr 1 = (1)/(C ) + (1)/(3.5)`
`rArr C = (3.5)/(2.5) = 1.4 muF`
