    In a choke coil, the reactance \[{{X}_{L}}\]and resistance R are such that

    A)  \[{{X}_{L}}=R\]

    B)         \[{{X}_{L}}>>R\]

    C)  \[{{X}_{L}}<<R\]             

    D)         \[{{X}_{L}}=\infty \]

    Correct Answer: B

    Solution :

    To decrease current in an AC circuit, choke coil is used. The choke coil has high inductance and negligible resistance, so that the energy loss in the circuit is negligible.       Hence,        \[{{X}_{L}}>>R\]
