  • question_answer
    What is the value of inductance L for which the current is maximum in a series LCR circuit with \[C=10\mu F\] and \[\omega =1000{{s}^{-1}}\]?

    A) 1 mH

    B) cannot be calculated unless R is known

    C) 10 mH        

    D) 100 mH

    Correct Answer: D

    Solution :

    [d] Condition for which the current is maximum in a series LCR circuit is, \[\omega =\frac{1}{\sqrt{LC}}\] \[1000=\frac{1}{\sqrt{L(10\times {{10}^{-6}})}}\Rightarrow L=100\,mH\]
