    Which of the following combinations should be selected for better tuning of an L-C-R circuit used for communication?

    A)  \[R=20\Omega ,L=1.5\text{ }H,C=35\mu F\]

    B)  \[R=25\Omega ,L=2.5H,C=45\mu F\]

    C)  \[R=15\Omega ,L=3.5H,C=30\mu F\]

    D)  \[R=25\Omega ,L=1.5\text{ }H,C=45\mu F\]

    Correct Answer: C

    Solution :

    Better tuning means low bandwidth \[=\frac{\overset{-}{\mathop{R}}\,}{L}\]
