Pure R, L and C Circuits

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

Show answer and solution

Answer: (a)

  1. For a.c.: XL=ωLX_L = \omega L (finite). For d.c.: ω=0\omega = 0, so XL=0X_L = 0.
  2. Ratio =ωL0=∞= \frac{\omega L}{0} = \infty
  3. So the answer is (a) ∞\infty.
