Answer» Correct Answer - A In Fig., the two condensers are in series and so are the two inductors. Therefore, `L_(s) = L + L = 2 L` `(1)/(C_(s)) = (1)/(C ) + (1)/(C ) = (2)/(C ) , C_(s) = C//2` `:.` Natural frequency of the circuit, `v = (1)/(2 pi sqrt(L_(s) C_(s))) = (1)/(2 pi sqrt(2 L xx C //2)) = (1)/(2 pi sqrt(LC))` |
