In a series LCR circuit an ac voltage source is connected. When inductor is removed from the circuit, the phase difference between the voltage and the current in the circuit is \(\frac{π}{3}\). If capacitor is removed from the circuit instead of inductor, the phase difference is again \(\frac{π}{3}\). What is the power factor of the circuit?- \(\frac{1}{\sqrt3}\)
- \(\frac{1}{2}\)
- \(\frac{\sqrt3}{2}\)
