Question

In an electrical circuit R, L, C and an a.c. 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 ciruit is π3 . If instead, C is removed from the circuit, the phase difference is again π3 . The power factor of the circuit is
