Pure R, L and C Circuits

A coil has inductive reactance $3$ H. The ratio of its reactance when it is first connected to an a.c. source and then to d.c. source is

Show answer and solution

Answer: (c)

For a.c.: $X_L = \omega L$ , a finite value.
For d.c.: $\omega = 0$ , so $X_L = 0$ .
Ratio $= \frac{\omega L}{0} = \infty$
So the answer is (c) infinite.
