  • question_answer
    Of the following about capacitive reactance which is correct?

    A) The reactance of the capacitor is directly proportional to its ability to store charge

    B) Capacitive reactance is inversely proportional to the frequency of the current

    C) Capacitive reactance is measured in farad

    D) The reactance of a capacitor in an A.C. circuit is similar to the resistance of a capacitor in a D.C. circuit

    Correct Answer: B

    Solution :

    [b] \[{{X}_{C}}=\frac{1}{\omega C}\Rightarrow {{X}_{C}}\alpha \frac{1}{\omega }\] for given C.
