Question

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?

• A. $\frac{1}{\sqrt3}$
• B. $\frac{1}{2}$
• C. $\frac{\sqrt3}{2}$
• D. 1
