Physics Question from JEE Main 2023 · 29 January, Shift 2

For the given figures, choose the correct option:

Two AC circuits labeled (a) and (b). Circuit (a) has a 40 ohm resistor with 220 V, 50 Hz source. Circuit (b) has 40 ohm resistor, 50 mH inductor, 0.5 microfarad capacitor, and 220 V, 50 Hz source.
  • A

    The rms current in circuit (b) can never be larger than that in (a)

  • B

    The rms current in figure (a) is always equal to that in figure (b)

  • C

    The rms current in circuit (b) can be larger than that in (a)

  • D

    At resonance, current in (b) is less than that in (a)
