$A$ series $LCR$ circuit is resonating with a source whose emf varies with time as described in diagram $-1$. If we replace the source by another source whose emf varies with time according to diagram $-2$,then:

  • A
    for getting resonance again,decrease $R$
  • B
    current will remain in phase with source voltage
  • C
    for getting resonance again,decrease $C$
  • D
    current will lead source voltage after replacing the source
