Alternating Current question

2020 · Q160

NEETPhysicsAlternating CurrentMCQ+4 / −1
A series LCR circuit is connected to an ac voltage source. When L is removed from the circuit, the phase difference between current and voltage is π3{\pi \over 3}3π​. If instead C is removed from the circuit, the phase difference is again π3{\pi \over 3}3π​ between current and voltage. The power factor of the circuit is :
  1. A
    0.5
  2. B
    1.0
  3. C
    −-− 1.0
  4. D
