An inductor of inductance $\displaystyle 2$ mH is connected to a $\displaystyle 220$ V, $\displaystyle 50$ Hz a.c. source. Let the inductive reactance in the circuit is $\displaystyle X_1$. If a $\displaystyle 220$ V dc source replace the ac source in the circuit, then the inductive reactance in the circuit is $\displaystyle X_2$. $\displaystyle X_1$ and $\displaystyle X_2$ respectively are :
