Three capacitors are connected of `1muF,2muF` and `3muF` are joined is series first and then in parallel. Calculate the ratio of equivalent capacitance in two cases.

Text Solution

Verified by Experts

`C_1=1muF,C_2=2muF,C_3=3muF`
Series:
`1/C_s=1/C_1+1/C_2+1/C_3`
`=1/1+1/2+1/3`
`(6+3+2)/6 =11/6`
`:.C_s=6/11muF`
Parallel `C_P = C_1+C_2+C_3`
`=1+2+3 =6 muF`
Ratio of `C_s/C_P=6/(6xx11)=1/11`
