The differeence in the effective capacity of two similar capacitor when joined in series and then in paralllel is 6 `mu` F the capacity of each capacitor is

`2muF`

`4muF`

`8muF`

`16muF`

Text Solution

Verified by Experts

The correct Answer is:

`C_(p)-C_(s)=6("But"C_(p)=n^(2)C_(s))`
`therefore" "n^(2)C_(s)-C_(s)=6`
`4xxC/2-C/2=6`
`2C-C/2=6`
`(3C)/2=6`
`therefore" "C=4muF`
