    Power factor is maximum in an LCR circuit when [RPET 2000]

    A)            \[{{X}_{L}}={{X}_{C}}\]     

    B)            \[R=0\]

    C)            \[{{X}_{L}}=0\]                    

    D)            \[{{X}_{C}}=0\]

    Correct Answer: A

    Solution :

               In LCR circuit; in the condition of resonance \[{{X}_{L}}={{X}_{C}}\] i.e. circuit behaves as resistive circuit. In resistive circuit power factor is maximum.
