In an electrical circuit R,L,C and an AC voltage source are all connected in series.

In an electrical circuit R,L,C and an AC voltage source are all connected in series. When L is removed from the circuit, the phase difference between the voltage and the current in the circuit is π/3. if instead, C is removed from the circuit, the phase difference is again π/3. The power factor of the circuit is

  • Here in both case the phase difference is same that means inductive and capacitative reactance are same as R is constant as Xl=Xc the Z=R cos is R/Z is 1
