An inductor has an inductive reactance of 250 v when is connected to a 400 Hz line . what will be the inductance reactance?

Inductive reactance (X_L) is calculated using the formula (X_L = 2\pi f L), where (f) is the frequency in hertz and (L) is the inductance in henries. Given that the inductive reactance is 250 ohms and the frequency is 400 Hz, we can rearrange the formula to find the inductance: (L = \frac{X_L}{2\pi f}). Plugging in the values, we get (L = \frac{250}{2\pi \times 400} \approx 0.0994 , \text{H}) or 99.4 mH.
