Inductive Reactance Calculator
An ideal inductor opposes alternating current with a reactance that rises in proportion to frequency. Its impedance is purely imaginary and positive: the voltage leads the current by 90°.

Use this inductor in the AC & RLC Lab
Carries L and f; the Lab asks for R and C.
Technical reference
XL = ω·L = 2π·f·L
Z_L = j·XL, |Z_L| = XL, φ = +90°
- L
- inductance (> 0)[H]
- f
- frequency (≥ 0)[Hz]
- XL
- inductive reactance[Ω]
Reference: L = 0.1 H, f = 50 Hz → XL = 31.4159 Ω.
Ideal inductor: no winding resistance or core loss.
