Physics Question from JEE Main 2025 · 22 January, Shift 2

A series LCR circuit is connected to an alternating source of emf EE. The current amplitude at resonance frequency is I0I_0. If the value of resistance RR becomes twice of its initial value, then amplitude of current at resonance will be:

  • A

    I02\frac{I_0}{2}

  • B

    2I02I_0

  • C

    I0I_0

  • D

    I02\frac{I_0}{\sqrt{2}}
