    The phase difference between the current and voltage of LCR circuit in series combination at resonance is [CPMT 1999; Pb. PET 2001]

    A)            0    

    B)            \[\pi /2\]

    C)            \[\pi \]                                    

    D)            \[-\pi \]

    Correct Answer: A

    Solution :

               At resonance LCR series circuit behaves as pure resistive circuit. For resistive circuit \[\varphi ={{0}^{o}}\]
