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 circuit is \[\pi /3\]. If instead, C is removed from the circuit, the phase difference is again\[\pi /3\]. What is the power factor of the circuit?
