What is inductive reactance `X_(1)` ? How does it depend on frequence ? Give its unit.

Explanation

The resistance offered by the inductor, called inductive reactance `(X_(1)).` It is measured in ohm.
`X_(L)=omega_(L)`
`X_(L)=2pifL`
where f is the frequency of the alternating current. For a steady current, f = 0. Therefore, `X_(L)=0.` Thus an ideal inductor offers no resistance to steady DC current.
