Inductors

Inductive Reactance

  • When an a.c. voltage is applied to an inductor the ratio of voltage to current is the reactance (XL) measured on Ohms (Ω)
    • XL = V ÷ I
    • I = V ÷ XL
    • V = I × XL
  • Reactance depends on the value of the inductor and also increases with frequency XL = 2πƒL
