In a series LR circuit $\displaystyle X_L=R$ and power factor of the circuit is $\displaystyle P_1$. When capacitor with capacitance $\displaystyle C$ such that $\displaystyle X_L=X_C$ is put in series, the power factor becomes $\displaystyle P_2$. The ratio $\displaystyle \frac{P_1}{P_2}$ is :
Official answer
(2)
$\displaystyle \frac{1}{\sqrt{2}}$
