Four condensers having capacities 2pF, 3pF, 4pF and 6pF are connected in series. The equivalent capacity of the combination is

8.0 pF

0.8 pF

1.8 pF

0.4 pF

Text Solution

Verified by Experts

The correct Answer is:

`1/C_(S)=1/C_(1)+1/C_(2)+1/C_(3)+1/C_(4)`
`=1/2+1/3+1/4+1/6`
`therefore" "C_(S)=0.8pF.`
