Three capacitor of capacitance C(mu F) a...

Three capacitor of capacitance `C(mu F)` are connected in parallel to which a capacitor of capacitance C is connected in series. Effective capacitance is 3.75. then capacity off each capacitor is

A

`4muF`

B

`5muF`

C

`6muF`

D

`8muF`

Text Solution

Verified by Experts

The correct Answer is:
B

`C_(P)=C+C+C+=3C`
Now,`" "C_(S)=(C_(P)*C)/(C_(P)+C)`
`therefore" "3.75=(3CxxC)/(3C+C)" "thereforeC=5muF.`
