The capacitance of a capacitor that should be connected along with two capacitors, having capacitance `4 mu F and 8 mu F` all in series to produce effective capacitance of `(24)/(11) mu F` is :

A

A.`6 mu F`

B

B.`2 mu F`

C

C.`110 muF`

D

D.`12 muF`

Text Solution

Verified by Experts

The correct Answer is:
D
`1/C_s = 1/C_1+1/C_2+1/C_3 `
`11/24 = 1/4 + 1/8 + 1/C_3`
`:. C_3 = 12muF`
