  • question_answer
    In a series LCR circuit, different physical quantities vary with frequency v. Which of the following curves represent correct frequency variation of the corresponding quantity?

    A) Curve I for R and curve III for\[{{X}_{L}}\]

    B) Curve II for current I

    C) Curve III for \[{{X}_{L}}\] and curve IV for R

    D) Curve IV for \[{{X}_{C}}\]

    Correct Answer: A

    Solution :

    [a] : R is independent of frequency. Current becomes maximum at resonance. \[{{X}_{L}}=\omega L=2\pi \upsilon L\] \[{{X}_{C}}=\frac{1}{\omega C}=\frac{1}{2\pi \upsilon C}\]
