Reactance (Xl / Xc)

Compute frequency‑dependent opposition to AC by inductors and capacitors.

Formulas

  • Inductive Reactance: XL = 2πfL
  • Capacitive Reactance: XC = 1 / (2πfC)

Tips

  • Higher frequency increases XL but decreases XC
  • In AC analysis, impedance Z combines R with X (vector sum)
