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