Seven capacitors, each a of a cpacitance `2muF`, are to be connected in a configuration to obatin an effective capacitance of `((16)/(13))muF`. Which of the combinations, shown in figure below, will achieve the desired value ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C

`C_(12)=6muF`
`C_(23)=(2)/(4)=(1)/(2)muF`
`C_(13)=(6xx(1)/(2))/(6+(1)/(2))=(3)/((13)/(2))=(6)/(13)muF`.
