In an electrical circuit R L C and 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 $\pi/3$. The power factor of the circuit is $1/2$ $1/\sqrt{2}$ 1 $\sqrt{3}/2$
