    Which of the following graphs represents the correct variation of capacitive reactance \[{{X}_{C}}\] with frequency v?      

    A)           

    B)

    C)

    D)

    Correct Answer: C

    Solution :

    [c] Capacitive reactance, \[{{X}_{C}}=\frac{1}{\omega C}=\frac{1}{2\pi vC}\] \[\Rightarrow \,\,{{X}_{L}}\propto \frac{1}{v}\] With increases in frequency, \[{{X}_{C}}\] decreases, Hence, Option [c] represents the corrent graph.
