Question

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