  1. A
    The current will be in phase with the voltage if ω=104rad.s−1\omega = {10^4}rad.{s^{ - 1}}ω=104rad.s−1
  2. B
    The frequency at which the current will be in phase with the voltage is independent of RRR
  3. C
    At ω∼0\omega \sim 0ω∼0 the current flowing through the circuit becomes nearly zero
  4. D
    At ω>>106rad.s−1,\omega \gt \gt {10^6}rad.{s^{ - 1}},ω>>106rad.s−1, the circuit behaves like a capacitor
