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 $\displaystyle \pi / 3$. If instead, C is removed from the circuit, the phase difference is again $\displaystyle \pi / 3$. The power factor of the circuit is :
